Rare Earth Metals

Rare earth element (REE) or rare earth metal is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium.  Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties.

Scandium Oxide Sc2O3

Scandium oxide is the primary form of refined scandium produced by the mining industry, making it the start point for all scandium chemistry. Scandium oxide reacts with most acids upon heating, to produce the expected hydrated product.
