Switching From Ferrite Magnets to Rare Earth Magnets

Switching From Ferrite Magnets to Rare Earth Magnets Switching from traditional ferrite magnets to rare earth magnets is no small thing. Magnets are measured by their BHmax score. The higher the number the stronger the magnet. Most traditional ferrite magnets will have a BHmax of no higher than 3.5. A rare earth magnet can have a BHmax of up to 40, more than ten times stronger! Any time that you…

A Study on Synthesis, Structural and Magnetic Properties of La2O3 Doped Isotropic Ba-M Ferrites_Crimson Publishers

A Study on Synthesis, Structural and Magnetic Properties of La2O3 Doped Isotropic Ba-M Ferrites by Zubair Ahmad* in Crimson Publishers: Peer Reviewed Material Science Journals 

Present work reports the synthesis, structural and magnetic properties of BaFe11O17.5 and La2O3 doped  (Ba La0.05Fe11O17.575, BaLa0.1Fe11O17.65, BaLa0.2Fe11O17.80 and BaLa0.3Fe11O17.95) ferrites produced through powder metallurgy method with escalated magnetic properties. Phase evaluation, crystal structure, microstructure, and magnetic properties thermomagnetic characteristics for the La doped and La free ferrites have been investigated at varying sintered temperatures. XRD studies revealed that BaFe12O19 phase is formed at 900  ̊C through the reaction of Fe2O3 and BaFe2O4. Electron microscopy studies elucidated that microstructural features depend critically on the heat treatment conditions as well as La content. La addition up to 1.0 mole found to be beneficial to refine particle size close to single domain wall size, which, in turn, led to enhance magnetic properties of the ferrite. Optimum magnetic properties for the La free BaFe11O17.5 are Hc=4.4kOe, Br=1.9kG, and (BH)max=0.85MGOe which were improved to Hc=4.9kOe, Br=2.4kG and (BH)max=1.2MGOe with La2O3 additive. The La2O3 acts as a grain growth inhibitor and led to enhance high coercivity of 4.9kOe in the ferrite. The dielectric constant and dielectric loss factor decrease monotonically with increasing applied frequency at the constant temperature. Permeability is found to be sensitive to density and microstructural components like grain size and porosity of the sintered ferrites.

What are neodymium magnets?

First there were ferit magnets.

Classic ferrite magnets known to us since childhood. Probably everyone played with magnets, admiring their strength. Some samples were quite strong, they were used to create powerful speakers, from where they were most often extracted by curious children. The bonding strength of ferrite magnets is quite high, there is a relationship between the dimensions and the bonding layer. Ferrite magnets have been used for a variety of purposes, including industrial ones. Their main advantages were:

1.      Resistance to corrosion and atmospheric moisture;

2.      Resistance to demagnetization;

3.      Low cost of production;

4.      Easy to machine.

5.      As for the shortcomings, they are as follows:

6.      Weak magnetic field;

7.      Fragility, lack of resistance to blows.

The basis of ferrite magnets is the natural material magnetite, which is subjected to appropriate processing - additives such as cobalt oxide are added to it. The first ferrite magnets contained barium, subsequently replaced by strontium, which made the manufacture of magnets cheaper and easier. In subsequent years, the technology for manufacturing ferrite magnets was improved, but it was impossible to achieve a very high adhesion force. A radical change in the technology of magnet production took place in the 1980s, when the first neodymium magnets appeared, which significantly exceeded their ferrite counterparts by the coercive force.

Then a neodymium magnet appeared

Neodymium magnets were originally produced in Japan and the United States of America. They were discovered in the research laboratories of these countries and are a combination of the following chemical elements: boron, iron and metal from the lanthanoid group - neodymium. This chemical element belongs to the rare earth group and is the main link in the neodymium magnet. The element boron is added to the magnets in fairly small quantities. The bonding strength of neodymium magnets is incredibly high, it significantly exceeds the bonding strength of ordinary ferrite magnets. If you take two large pieces of neodymium alloy and ensure that they are in contact with each other, then breaking them with your bare hands will be almost impossible.

The first neodymium magnets went on sale in the 1990s. They were and remain quite expensive, the cost of the most powerful samples reaches several thousand rubles. This is due to the fact that the amount of neodymium in the rock workings is small. This is what affects the final cost. In addition, developer patents have an effect on cost.

What are neodymium magnets

Neodymium magnets can take the form of rings, disks, balls or rectangles, and much less often in other forms. Depending on the destination, one or another form is chosen. In addition, the ingredients of neodymium magnets can turn into magneto plastics with flexibility. Magnetic vinyl, used for the production of souvenirs and magnets for refrigerators, is also a magnetoplast. It is very difficult to give the formed magnet any other shape - this will require special equipment.

How to make neodymium magnets?

Most neodymium magnets available commercially are produced by sintering in special furnaces. This is a very complex and painstaking process that takes place in an inert atmosphere or in a vacuum. The basis of magnets, as already mentioned, are neodymium, iron and boron. Production proceeds in several stages:

Powdery ingredients

·         Pressing powders and shaping the future magnet;

·         Setting the direction of the magnetic field;

·         Sintering of powdered ingredients and magnetization.

Behind the apparent simplicity lies the work of dozens of people and dozens of pieces of equipment. The task of manufacturers is not only to give the magnet a certain shape and form a magnetic field of the necessary strength. Consumers may also need more unusual properties, such as resistance to high temperatures.

How to buy neodymium magnets?

There are many varieties of sintered neodymium magnets. They differ in traction, maximum operating temperature and dimensions. Magnetic energy is a static parameter and does not change when the magnet is resized, as it might seem at first glance. The thing is that the adhesion strength is highly dependent on the following factors:

1.      Magnetic properties of metals;

2.      The cleanliness and curvature of the metal surface;

3.      The area of ​​the working side of the magnet;

4.      Dimensions of the magnet;

5.      The presence of a magnet in the metal body (allows you to form a narrower directivity of the magnetic field);

6.      Airhumidity.

Thus, the larger the magnet and the larger its working surface area, the stronger it will be attracted to the metal surface. If the surface of the metal is streaked with bumps and covered with rust, the adhesion will drop. In this case, the magnetic energy will remain the same. This parameter is indicated by the number in the magnet brand

Magnetic Materials

All types of materials and substances posses some kind of magnetic properties which are listed further down in this article. But normally the word “magnetic materials” is used only for ferromagnetic materials ( description below), however, materials can be classified into following categories based on the Paramagnetic materials

The materials which are not strongly attracted to a magnet  are known as paramagnetic material. For example: aluminium, tin magnesium etc. Their relative permeability is small but positive. For example: the permeability of aluminium is: 1.00000065.  Such materials are magnetized only when placed on a super strong magnetic field and act in the direction of the magnetic field.

Paramagnetic materials have individual atomic dipoles oriented in a random fashion as shown below:

Magnetic Domains in Paramagnetic Materials

The resultant magnetic force is therefore zero. When a strong external magnetic field is applied , the permanent magnetic dipoles orient them self parallel to the applied magnetic field  and give rise to a positive magnetization. Since, the orientation of the dipoles parallel to the applied magnetic field is not complete  , the magnetization is very small.

Magnetic field through a paramagnetic material

2. Diamagnetic materials

The materials which are repelled by a magnet such as zinc. mercury, lead, sulfur, copper, silver, bismuth, wood etc., are known as diamagnetic materials. Their permeability is slightly less than one. For example the relative permeability of bismuth is 0.00083, copper is 0.000005 and wood is 0.9999995. They are slightly magnetized when placed in a very string magnetic field and act in the direction opposite to that of applied magnetic field.

In diamagnetic materials , the two relatively weak magnetic fields caused due to the orbital revolution and and axial rotation of electrons around nucleus are in opposite directions and cancel each other. Permanent magnetic dipoles are absent in them, Diamegnetic materials have very little to no  applications in electrical engineering.

Magnetic field through a diamagnetic material

3. Ferromagnetic materials

The materials which are strongly attracted by a magnetic field or magnet is known as ferromagnetic material for eg: iron, steel , nickel, cobalt etc. The permeability off these materials is very very high ( ranging up to several hundred or thousand).

The opposite magnetic effects of electron orbital motion and electron spin do not eliminate each other in an atom of such a material. There is a relatively large contribution from each atom which aids in the establishment of an internal magnetic field, so that when the material is placed in a magnetic field, it’s value is increased many times thee value that was present in the free space before the material was placed there.

For the purpose of electrical engineering it will suffice to classify the materials as simply ferromagnetic and and non-ferromagnetic materials. The latter includes material of relative permeability practically equal to unity while the former have relative permeability many times greater than unity. Paramagnetic and diamagnetic material  falls in the non-ferromagnetic materials.

Soft Ferromagnetic materials

They have high relative permeability, low coercive force, easily magnetized and demagnetized and have extremely small hysteresis. Soft ferromagnetic materials are iron and it’s various alloys with materials like nickel, cobalt, tungsten and aluminium . ease of magnetization and demagnetization makes them highly suitable for applications involving changing magnetic flux as in electromagnets, electric motors, generators, transformers, inductors, telephone receivers, relays etc. They are also useful for magnetic screening. Their properties may be greatly enhanced through careful manufacturing and and by heating and slow annealing so as to achieve a high degree of crystal purity. Large magnetic moment at room temperate makes soft ferromagnetic materials extremely useful for magnetic circuits but ferromagnetics are very good conductors and suffer energy loss from eddy current produced within them. There is additional energy loss due to the fact that magnetization does not proceed smoothly but in minute jumps. This loss is called magnetic residual loss and it depends purely on the frequency of the changing flux density and not on it’s magnitude.

b. Hard Ferromagnetic materials

They have relatively low permeability, and very high coercive force. These are difficult o magnetize and demagnetize. Typical hard ferromagnetic materials include cobalt steel and various ferromagnetic alloys of cobalt, aluminium and nickel. They retain high percentage of their magnetization and have relatively high hysteresis loss. They are highly suited for use as permanent magnet as speakers, measuring instruments etc.

4. Ferrites

Ferrites are a special group of ferromagnetic materials that occupy an intermediate position between ferromagnetic and non-ferromagnetic materials.  They consist of extremely fine particles of a ferromagnetic material possessing high permeability , and are held together with a binding resin. The magnetization produced in ferrites is large enough to be of commercial value but their magnetic saturation are not as high as those of ferromagnetic materials. As in the case of ferromagnetics, ferrites may be soft or hard ferrites.

a. Soft Ferrites

Ceramic magnets also called ferromagnetic ceramics, are made of an iron oxide, Fe2O3, with one or more divalent oxide such as NiO , MnO or ZnO. These magnets have a square hysteresis loop and high resistance and demagnetization are valued for magnets for computing machines where a high resistance is desired. The great advantage of ferrites is their  high resistivity. Commercial magnets have resistivity as high as 10^9 ohm-cm. Eddy currents resulting from an alternating fields are therefore, reduced to minimum, and the range of application of these magnetic materials is extended to high frequencies , even to microwaves . Ferrites are carefully made by mixing powdered oxides, compacting and sintering at high temperature. High-frequency transformers in televisions and frequency modulated receivers are almost always made with ferrite cores.

b. Hard Ferrites

These are ceramic permanent magnetic materials. The most important family of hard ferrites has the basic composition of MO.Fe2O3 where M is barium(Ba) ion or strontium (Sr) ion. These materials have a hexagonal structure and low in cost and density. Hard ferrites are used in generators, relays and motors. Electronic applications include magnets for loud speakers, telephone ringers and receivers. They are also used in holding devices for door closer, seals, latches and in several toy designs.

Something about NdFeB Magnets

NdFeB Magnets was developed in the year 1982 by General Motors and Sumitomo Special Metals and made available for commercial use in late 1984. NdFeB magnets are the finest and the strongest permanent magnet available commercially today, and also, the magnet is extensively used worldwide. There are two principal ways of manufacturing NdFeB magnets: Sintered magnet process and bonded magnet process. Sintered magnets display a stronger magnetic force and high performance as compared to bonded magnets. In a sintered magnet process, the NdFeB powder is compacted and then sintered and is fused into solid material and sintered magnet requires a finishing product or operation while in a bonded magnet, the magnet’s powdered form is blended with other required materials and then heated and finally cut to sizes and shapes, etc. Bonded magnets do not require any finishing products or operations as they are the final products. Rare Earth Neodymium Disc Magnet are also available in different types of grades, and these grades are based on the maximum energy output. Many of these grades support a variety of industrial and commercial applications; this grade allows for magnetic performance, operational temperature resistance and balancing the cost of the NdFeB magnets. These magnets have replaced alnico, and ferrite magnets in modern technology products since NdFeB magnets proved to be more effective, efficient, powerful as compared to other magnets and also the NdFeB magnets are available in the variety of shape and sizes. The fact that these magnets have 10 times the powers to its size has contributed to its high demand. These magnets, however, have very weak resistance against corrosion, and so a three-level Nickel-copper-Nickel coating is recommended. Many NdFeB Magnets manufacturers have their own types of plating or coating, be it two layered or three-layered coating depending on the types of environment as the effectiveness of the coating may differ to various other environments.

Why Select Magnet

A magnet is defined as an object which is capable of producing a magnetic field and attracting unlike poles and repelling like poles.

There are many types of magnets, which are generally divided into two categories: hard (permanent) magnets (magnetic retention for a long or permanent time) and soft magnets (magnetic for a short period of time). The magnets we call generally refer to permanent magnets.

Various types of magnets are used differently in various fields.

Magnets are used in maglev trains, the Electroacoustic industry(Speakers, signal receivers, microphones, alarm systems, professional stage audio, car audio, etc.) , microwave communication(Radar detection technology, satellite communication, remote control technology, electronic device tracking, electronic countermeasure technology must be applied, magnetron rectifier, magnetron wave tube, cathode ray, circulator, etc.) , Special tool metal material(Magnetized wax inhibitor, pipeline descaling device, magnetic fixture, electric mahjong table, magnetic lock, window, and door magnet, luggage leather magnet, luggage leather magnet, small toy magnet, special tool magnet, processing gift box packaging, etc.) , magnet therapy (Magnetic therapy cups, magnetic balls, magnetic therapy machines, magnetic therapy shoes, magnetic therapy caps, magnetic therapy bracelets, necklaces, etc.), new energy vehicle

(2) Ferrite permanent magnett material (Ferrite)

Magnet sort by shapes.

Tile-shaped magnets(Arc shape), special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, block magnets, and various shapes can be punched holes.

Classification by production process

Rare earth permanent magnet material

Rare earth permanent magnet materials (NdFeB Nd2Fe14B) are divided into the following three types according to different production processes:

(1) Bonded NdFeB (Bonded NdFeB)

Bonded NdFeB is a composite NdFeB permanent magnet made by uniformly mixing NdFeB powder with binders such as resin, plastic, or low melting point metal, and then compressing, extruding, or injection molding. The product is formed once, without secondary processing, and can be directly made into various complex shapes. The bonded NdFeB has magnetism in all directions and can be processed into NdFeB compression molds and injection molds. High precision, excellent magnetic properties, good corrosion resistance, and good temperature stability.

(2) Sintered NdFeB (Sintered NdFeB)

The sintered NdFeB permanent magnets are smelted by jet milling and powder, with high coercivity value and extremely high magnetic properties. Its maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. Its own mechanical properties are also quite good, and it can be cut into different shapes and drilled. High-performance products have a maximum operating temperature of up to 200°C.

Because of its substance content, it is easy to cause rust, so different coating treatments must be applied to the surface according to different requirements. (Such as galvanized, nickel, environmentally friendly zinc, environmentally-friendly nickel, nickel-copper-nickel, environmentally-friendly nickel-copper-nickel, etc.). Very hard and brittle, with high resistance to demagnetization, high cost/performance ratio, not suitable for high operating temperatures (>200°C).

(3) Injection NdFeB (Zhusu NdFeB)

With extremely high precision, it is easy to make thin-walled rings or thin magnets with complex anisotropic shapes.

Widely Application Industries

Electroacoustic field: speakers, receivers, microphones, alarms, stage audio, car audio, etc.

Electronic appliances: permanent magnet mechanism vacuum circuit breakers, magnetic latching relays, watt-hour meters, water meters, sound meters, reed switches, sensors, etc.

Motor field: VCM, CDDVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors, etc.

Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc.

Healthcare: nuclear magnetic resonance apparatus, medical equipment, magnetic therapy health care products, magnetized fuel saver, etc.

Other industries: magnetized wax inhibitor, pipe descaler, magnetic fixture, automatic mahjong machine, magnetic lock, door and window magnet, luggage magnet, leather magnet, toy magnet, tool magnet, craft gift packaging, etc.

This affects the performance of bonded magnets. The bonded Nd-Fe-B magnet is formed by injection molding; therefore, it contains adhesives. The density of adhesives is generally 80% of the theoretical density. Sintered Nd-Fe-B magnets are heated at high temperatures through complex processes. Therefore, the magnetism of bonded Nd-Fe-B magnets decreases by about 30% compared to that of sintered Nd-Fe-B magnets.

Bonded Magnet Market: Prominent Segments

Based on product type, the ferrite bonded magnets segment held major share of the global bonded magnet market in 2019. This trend is anticipated to continue during the forecast period.
