Erbium Oxide Powder Introduction
Erbium oxide is a pink powder in appearance. It is insoluble in water but soluble in acid. Erbium oxide can be used as control material of nuclear reactor, additive material of yttrium iron garnet, rose red colorant of glass, infrared absorption, and special luminescent glass.
Erbium Oxide Powder Applications
Erbium oxide can be used as an additive of yttrium iron garnet and control material of nuclear reactor. It can also be used to make special luminescent glass and infrared absorbing glass. It can also be used as a glass colorant to make rose-red glass color.
