Production Process of Scandium Oxide

What’s Scandium Oxide powder?

The most significant product in scandium products is the Scandium Oxide. The physical and chemical characteristics of Scandium oxide are identical to that of rare earths oxides. Therefore, production processes are similar. Sc2O3 may produce metal scandium and other scandium alloys under certain environmental conditions. Scandium oxide has many uses in aerospace, aluminum alloys, electric light source and lasers as well as ceramics and ceramic activators.

Scandium Resources in Nature

Scandium is found in approximately 800 different minerals. There are very few scandium-containing mineral species, mostly due to the interaction with other minerals. You can find many minerals that are scandium-rich, including phosphorite and wolframite as well as rare earth ores, vanadium-titanium magneticite, rare Earth iron ores, manganese depleted ores and tin. The mine that contains the highest amount of scandium is bauxite.

Materials Used in the Production of Scandium Oxide Powder

Scandium oxide raw materials are mostly scandium-containing liquids, such as waste residue or soot in metalurgical, and scandium concentrate that has been obtained from vanadium–titanium magite beneficiation.

1. The majority of the tungsten-extracted waste is contaminated with scandium. Scandium oxide 0.05%) can be found in the original ore of wolframite. Scandium oxide is 150600 g/t after the extraction. Pretreatment involves dissolving the waste in hydrochloric acids. The resulting ScCl3 solution then becomes the raw material to obtain scandium oxide.
2. A waste liquid containing scandium (mainly after the extraction of titanium form ilmenite) is considered to be sandium. Scandium oxide 15-20g/m3 is the primary raw material to extract scandium dioxide from ilmenite.
3. Scandium-containing soot is mainly the soot that has been chlorinated to sponge titanium. Pretreatment of the soot results in acid-dissolved scandium liquid, which is used as the raw material to extract scandium oxide.
4. Scandium concentrate, primarily scandium concentrate after vanadium-titanium magite beneficiation. Sc 27g/t of vanadium magnetite is present, while Sc 112-114g/t can be found in the beneficiated scandium concentrate. ScCl3 is obtained by dissolving the scandium concentrate in hydrochloric acids. It is used as raw material to extract scandium dioxide.
