Application of Terbium Metal
Terbium Metal is the important additive for NdFeB permanent magnets to raise the Curie temperature and improve temperature coefficiency. Another most promising use of distilled Terbium Metal, code 6563D, is in the magnetostrictive alloy TEFENOL-D. There are also other applications for some special master alloys. Terbium is primarily used in phosphors, particularly in fluorescent lamps and as the high intensity green emitter used in projection televisions. Terbium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder.
