About Erbium

Erbium is a chemical element and one of the lanthanides. It is a soft metal of light grey color and it can be obtained from various minerals like bastnaesites, and others. Erbium was discovered by a Swedish scientist and named after a town in Sweden. It is quite reactive for a metal, but not toxic and has no essence for living organisms. This chemical element is mainly used in alloys with such metals as iron, vanadium, and others. The main fields of the applications of erbium include glass fiber production, welding, producing sunglasses, jewelry, etc.
