Erbium Oxide

Erbium Oxide

CAS #: 12061-16-4

Linear Formula: Er2O3

EC No.: 235-045-7

Erbium oxide is pink powder, chemical formula Er2O3, insoluble in water, soluble in acid. It absorbs water and carbon dioxide in the air. It is mainly used as YAG crystal additive and nuclear reactor control material. It is also used to make special luminescent glass and infrared absorbing glass. It is also used as glass colorant.

Application Area:

1. Used in the production of glass clarifiers and can also be used as colorants.

2. Er: YAG as a special scintillation crystal growth additive.

3. Used for nuclear reactor control materials.

About Erbium Oxide
About Erbium Oxide

The production method of Erbium(III) oxide is mainly oxalic acid precipitation method, that is, taking Erbium(III) chloride or Erbium(III) nitrate solution as raw material, adjusting the Ph value to 2 with oxalic acid, adding ammonia to precipitate out erbium oxalate, heating, curing, separation, washing, drying at 110 ℃, and burning at 900~1000 ℃ to form Erbium(III) oxide.
