Erbium

Erbium-Oxide

 

Erbium is a chemical element in the lanthanide series, with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements on Earth. 

Erbium’s everyday uses are varied. It is commonly used as a photographic filter, and because of its resilience it is useful as a metallurgical additive.
