Erbium was isolated in 1843 by Carl Mosander who obtained two metal oxides from Yttria. One of these was the pink erbium oxide. It was extracted in 1878 by Jean-Charles Galissard de Marignac. Erbium like Holmium is used as a neutron absorber in nuclear reactors. The oxide Erbia is used as a pink glaze in glass. It is a solid metal at room temperature with a melting point of 1529°c and a boiling point of 2868°c.
