Application
Erbium 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.
