Industrial grade lithium carbonate is an important industrial chemicalwidely used in batteries, metal oxides and other industries
1. Used as the raw material reagent for synthesis of other lithiumcompounds;
2. Used for production of ceramics and electrical insulating ceramics;
3. Used to manufacture heat-resistant ceramic coatings for combustionchambers and nozzles of injection engines;
4. Used as acid-resistant coatings for glaze, enamel, aluminum, cast ironand steel plates;
5. Used as a glass additive, and the glass mixed with lithium carbonate isof high strength and resistance to atmosphere;
6. Used as a flux for the aluminum manufacturing industry (used to improvethe yield of electrolytic cell);
7. Used as a flux for welding aluminum and magnesium;
8. Used as a part of the mixture of smoke;
9. Used for fuel cells;
10. Used as an additive in the cement industry to improve the acceleratedand rapid curing process;
11. As an emotional stabilizer in psychiatry, it is mainly used to treatdepression and depression.
