Scandium Oxide Powder
Scandium(III) oxide, Sc2O3, or Scandia, is a high melting rare earth oxide. It is used in the preparation of other scandium compounds and high-temperature systems (for its resistance to heat and thermal shock), electronic ceramics, and glass composition (as a helper material).
Scandium Oxide Powder Applications
Scandium oxide can be used as evaporation material for semiconductor coating, as well as variable wavelength solid-state laser, high-definition TV electron gun, and metal halide lamp.
