On this page I'll provide comprehensive data for Erbium. I hope you profit from it.
Erbium Overview
Name Origin
Named after the Swedish town, Ytterby.
Symbol
Er (Erbium)Description
Soft, malleable, silvery metal.
Discovery
Discovered By: Carl Mosander
Year: 1843
Location: Sweden
Sources
Found with other heavier rare earths in xenotime and euxerite.
Uses
Erbium oxide is used in ceramics to obtain a pink glaze. Also a few uses in the nuclear industry and as an alloying agent for other exotic metals. For example, it increases the malleability of vanadium.
