Erbium(III) sulfate is an erbium compound with the chemical formula Er2(SO4)3. It is a pink crystalline salt, readily absorbing water to form an octahydrate.[1] It is used as a colorant in glass manufacturing and porcelain enamel glazes, as well as a dopant in the production of optical fiber.[2]
Synthesis
Erbium sulfate can be prepared by dissolving erbium(III) oxide in sulfuric acid:[3]
- Er2O3 + 3 H2SO4 → Er2(SO4)3 + 3 H2O
