Erbium(III) oxide Usage And Synthesis
- Chemical PropertiesPink powder that readily absorbs moisture and carbon dioxide from the atmosphere. infusible. Insoluble in water; slightly soluble in mineral acids.
Erbium(III) oxide (Er2O3), a pink solid, is a compound of erbium sometimes used as a colouring for glasses and a dopant for optical fibres and optical amplifiers. It was partially isolated by Carl Gustaf Mosander in 1843, and first obtained in pure form in 1905 by Georges Urbain and Charles James.
- UsesErbium (III) oxide also called Erbia, an important colourant in glasses and porcelain enamel glazes. High purity Erbium Oxide are widely applied as dopant in making optical fibre and amplifier. It is particularly useful as an amplifier for fiber optic data transfer. Erbium Oxide has a pink color, and is sometimes used as a colorant for glass, cubic zirconia and porcelain. The glass is then often used in sunglasses and cheap jewelry.
Erbium (III) oxide is easy to produce other Erbium compounds with this material. It has been used to impart a pink shade to glass and porcelain.
