Dysprosium Oxide

Dysprosium oxide is white powder, which is raw material for metal dysprosium. Color of Dy2O3 would be slightly different due to purity. It is a kind of rare earth oxide.  Dysprosium trioxide is insoluble in water, however soluble in mineral acids.

Applications – What is dysprosium oxide used for

Dysprosium(III)  oxide is additive for yttrium iron and yttrium aluminum garnet, which could serve as control materials for nuclear reactors. It is raw material for preparation of dysprosium lamp that have property of high brightness and good lighting color. Due to its strong property of cathode emitting , dysprosium oxide is also used as cathode coating. It is raw material for metal dysprosium, glass, NdFeB permanent magnet. In functional ceramic, dysprosium oxide used in production of piezoelectric ceramics, semi-conductive ceramics and capacitor ceramics.
