Dysprosium Oxide Powder
Dysprosium oxide is a white crystalline powder in appearance. It is insoluble in water, soluble in acid and ethanol. Dysprosium oxide dew is easy to absorb carbon dioxide and change into dysprosium carbonate when placed in the air.
Dysprosium Oxide Powder Applications
Dysprosium oxide can be used as a raw material of dysprosium metal, glass, Nd-Fe-B magnet, a rare-earth metal, phosphor additive, long-term luminous material additive, metal halogen lamp, magneto-optical memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry.
