Chemical Properties
white powder(s); can be prepared by heating the oxalate or sulfate; more magnetic than ferric oxide; slightly hygroscopic; absorbs atmospheric H2O and CO2; used with nickel in cermets and as an evaporated film of 99.9% purity it is reactive to radio frequencies [HAW93] [MER06] [CER91]
Uses
Dysprosium trioxide is used with nickel in cermets, which are used as nuclear reactor control rods. It is also used in ceramics, glass, phosphors, lasers and dysprosium metal halide lamps. It is an important raw material to prepare dysprosium(III) salts via reaction with acids.
Uses
Dierbium trioxide also called Erbia, an important colourant in glasses and porcelain enamel glazes. High purity Dierbium trioxide are widely applied as dopant in making optical fibre and amplifier. It is particularly useful as an amplifier for fiber optic data transfer. Dierbium trioxide 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.
