Scandium Oxide Powder (Sc2O3), CAS 12060-08-1

Scandium oxide powder (Sc2O3) is a white, odorless powder that is commonly used as a raw material for the production of other scandium compounds, such as scandium metal, scandium fluoride, and scandium nitrate.

Scandium oxide is insoluble in water, but soluble in acids. It has a high melting point of 2,325 °C and a high thermal conductivity, making it useful in high-temperature applications. It is also used as a dopant in the production of solid-state lasers, as a component in the production of high-strength aluminum alloys, and as a catalyst in various chemical reactions.

Scandium oxide powder should be stored in a cool, dry place, away from heat sources and incompatible materials. Proper protective equipment, such as gloves and safety goggles, should be worn when handling this material.
