Lithium Carbonate 

Li₂CO₃, a salt; colorless crystals. Density, 2.11 g/cm³ at 0°C; melting point, 732°C (dissociation occurs at higher temperatures). It has low solubility in water (1.33 g in 100 g H₂O at 20°C). Pure lithium carbonate is produced by passing CO₂ through a solution of LiOH; in industry it is produced by the action of potash or soda on lithium salt solutions at temperatures of 80°-90°C.

Lithium carbonate is the most important lithium salt. It is the raw material for the production of other lithium compounds. Lithium oxide, Li₂O, formed from Li₂CO₃, is used in the glass-making and ceramics industries because of its ability to impart valuable properties (thermal and chemical stability; strength) to the materials. Lithium carbonate is also used in pyrotechnics, the production of plastics (as a catalyst), and ferrous metallurgy (desulfurization of steel).
