Dysprosium, Mary Soon Lee
dysprosium, AN 66, is a silvery-white rare earth metal. its name is derived from the greek dysprositos, meaning “hard to get at”, owing to the difficulty in separating and isolating this rare earth element. dysprosium is used to measure neutron flux, to fuel reactors, and to activate phosphors. terfenol-d is a magnetorestrictive alloy, meaning that it changes shape when a magnetic field is applied, and is used to manufacture underwater acoustic systems.
