Dysprosium oxide (CAS:1308-87-8)

Dysprosium oxide is a white powder, insoluble in water, soluble in acid. 

Application:

Used for making metal dysprosium material, glass, additive of ndfeb permanent magnet, also used for metal halogen lamp, magneto optical memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry. Dysprosium oxide can also be used as additive of ndfeb is a permanent magnet, the magnet to add 2 ~ 3% of dysprosium, the coercive force can be improved, the demand for dysprosium is not big, but with the increase of demand ndfeb magnet, it becomes necessary to add elements, grade must be in the 95 ~ 99. About 9%, demand is increasing rapidly. Dysprosium oxide is also used as a raw material for making metal dysprosium, glass, ndfeb permanent magnets of the additive, also used for metal halogen lamp, magneto optical memory materials, yttrium iron or yttrium aluminum garnet, atomic energy industry.

Dysprosium Oxide (Dy2O3) is a white, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers and dysprosium metal halide lamps.

It can react with acids to produce the corresponding dysprosium(III) salts:

Dy2O3 + 6 HCl → 2 DyCl3 + 3 H2O
