Erbium Oxide, a pink solid, is a compound of erbium sometimes used as a coloring for glasses and a dopant for optical fibres and optical amplifiers. It was partially isolated by Carl Gustaf Mosander in 1843, and first obtained in pure form in 1905 by Georges Urbain and Charles James.
Erbium oxide can be also used as a burnable neutron poison for nuclear fuel.
It can react with acids to form the corresponding erbium salts:
Er2O3 + 6 HCl → 2 ErCl3 + 3 H2O
