ERBIUM CHLORIDE Chemical Properties,Usage,Production

Chemical Properties

pink crystalline powder

Uses

Starting material for new edge-bridged octahedral M6 cluster compounds such as CsErTa6Cl18, for which electron and stability studies were performed.1

Uses

It is a starting material for new edge-bridged octahedral M6 cluster compounds which are used for electron and stability studies.

Uses

Erbium Chloride is an important colourant in glasses and porcelain enamel glazes. High purity Erbium Chloride is widely applied as dopant in making optical fibre and amplifier. It is particularly useful as an amplifier for fiber optic data transfer.

Preparation

Erbium(III) chloride is a powerful catalyst for the acylation of alcohols and phenols.
Neodymium chloride and Erbium(III) chloride were prepared by dissolving the corresponding oxides of high purity in hydrochloric acid and removing the excess of the latter by evaporation.

Safety Profile

Poison by intraperitoneal and subcutaneous routes. Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of Cl-. See also RARE EARTHS.
