Dysprosium Oxide

Dysprosium Oxide

CAS #: 1308-87-8

Linear Formula: Dy2O3

EC No.: 215-164-0

Dysprosium(III) oxide is a Inorganic compound with chemical formula of Dy2O3, white powder, density of 7.81g/cm3, melting point of 2408 ℃, insoluble in water and soluble in acid to form trivalent salts. It can be volatilized with steam, alkaline, toxic, irritating to eyes, respiratory tract and skin, and can absorb carbon dioxide in the air and generate water soluble salts with Mineral acid.

Application Area:

1. Used as an activator for long afterglow phosphors

2. Additives for special scintillation crystal growth, etc

3. It can also be used as a special scintillation ceramic additive, etc

4. Used for the production of dysprosium metal or dysprosium iron alloy.

About Dysprosium Oxide
About Dysprosium Oxide

The production method of Dysprosium(III) oxide is mainly oxalic acid precipitation, that is, Dysprosium(III) chloride or Dysprosium(III) nitrate solution is used as raw material, the Ph value is adjusted to 2 with oxalic acid, and dysprosium oxalate is precipitated by adding ammonia water. After heating, curing, separation, washing, drying at 110 ℃, and burning at 900~1000 ℃, Dysprosium(III) oxide is formed.
