DYSPROSIUM CAS 7429-91-6

1) As an additive for NdFeB permanent magnets, adding about 2 to 3% of dysprosium in this magnet can improve its coercive force, the demand for dysprosium in the past was not large, but with the increase in demand for neodymium NdFeB magnets, it has become a necessary addition element, and the grade must be 95 ~ 99. Around 9%, demand is also increasing .

(2) Dysprosium is used as a phosphor activator, trivalent dysprosium is a promising single luminescent center tri-primary color luminescent material activation ions, it is composed of two emission bands, one for yellow light emission, the other for blue light emission, dysprosium-doped luminescent material can be used as a tri-primary color phosphor.
(3) Dysprosium is the necessary metal raw material for the preparation of large magnetostrictive alloy Terfenol alloys, which can enable some precision activities of mechanical movement to be realized.
(4) Dysprosium metal can be used as a magneto-optical storage material, with high recording speed and reading sensitivity.
