Erbium ( III) oxide is a chemical compound selected from the group of the oxides.

History

Erbium (III ) oxide in 1843 partially ( as a mixture of several lanthanide oxides ) isolated by Carl Gustaf Mosander and 1905 first prepared in pure form by Georges Urbain and Charles James.

Production and representation

Erbium ( III) oxide can be recovered by combustion of erbium in air.

Properties

Erbium ( III) oxide is a hygroscopic pink powder that is insoluble in water. It has a cubic crystal structure.

Use

Erbium ( III) oxide is used for the coloration of glasses and ceramics. As it absorbs infrared light in the respective lenses, it is used for protective glasses in the glass and steel industry. It also serves as starting material for the preparation of pure erbium.
