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 also 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-containing, including bauxite phosphorite, Wolframite ilmenite and rare earth ore.
Materials Used in the Production of Scandium Oxide Powder
Scandium oxide raw materials are mostly scandium-containing water, waste residue, and soot from metallurgy. Also, scandium concentrate is obtained following the beneficiation vanadium–titanium magite.
1. The majority of the sandium-containing material is waste that has been left over from tungsten extraction. Scandium oxide 0.05%) can be found in the original ore of wolframite. Scandium oxide is 150 – 600 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 a “scadium-containing” fluid. Scandium oxide 15-20g/m3 is the primary raw material to extract scandium dioxide from ilmenite.
3. Scandium-containing soot is mainly the soot from sponge titanium’s chlorination. Pretreatment of the soot results in acid-dissolved scandium liquid, which is used as raw material to extract scandium oxide.
4. Scandium concentrate, mainly from scandium magnetite beneficiation. Sc 27g/t of vanadium magnetite is present, and Sc 112-114g/t after beneficiation. ScCl3 is obtained by dissolving the scandium concentrate in hydrochloric acids. It is used as raw material to extract scandium dioxide.
