Scandium Oxide

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(III) oxide is used as evaporation materials for semiconductor coating, optical coating. It also could be used in solid laser device of variant wavelength, telephone electron gun of fine definition,  metal halide lamp, solide oxide fuel cell. Scandium aluminum alloy or other scandium alloy produced from scandium oxide . Scandium(III) oxide own high property in solderability , thermotolerance , corrosion resistance and thermal stability, which is used 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 , scandium oxalate.
