Scandium oxide is a kind of rare earths metals oxide, which is used in the preparation of other scandium compounds as scandium carbonate, scandium nitride, scandium aluminum alloy.Scandium oxide uses get in high-temperature systems, electric ceramics and glass composition. Scandium oxide properties own cubic structure of rare earth sesquioxide . Scandium(III) oxide is produced through heating scandium salts, which does’t dissolve in water and soluble in heat acid,but after heating, scandium oxide is hard to dissolve. It react with hydrochloric acid to get scandium chloride. It is byproduct of other ore processing and scrap as wolframite , adelfolite , columbite-tantalite. Many scraps also contain faint scandium as tungsten scrap, titanium dioxide scrap. Scandium oxide is the primary form of refined scandium produced by the mining industry. It is start point for all scandium chemistry. Scandium oxide is raw material for scandium nitride, scandium fluoride, scandium boride and scandium chloride .
Synonyms:discandium trioxide, scandia, scandia (Sc2O3), scandium oxide (ScO1.5), scandium sesquioxide, scandium(3+) oxide

Scandium(III) oxide act as evaporation materials for semiconductor coating and optical coating. It also play a role in solid laser device of variant wavelength, telephone electron gun of fine definition, metal halide lamp and solide oxide fuel cell. It is raw material of scandium aluminum alloys or other scandium alloys . Scandium(III) oxide own high property in solderability , thermotolerance , corrosion resistance and thermal stability, which play a role in aerospace , bicycle , vessel and so on. Scandium(III) oxide is also raw material for metal scandium, scandium salts as scandium chloride, scandium fluoride, scandium iodide and scandium oxalate.
