Chemical property 1. insoluble in alcohol and acid. It is heat stable below 600 C, and partially decomposes into lithium oxide and carbon dioxide at 618 C.

Product use

Uses 1. For the treatment of manic psychosis, production of sedatives, etc. It is the raw material for the preparation of lithium compounds and metal lithium. It can be used as bath additive in aluminium smelting. It is widely used in glass, ceramics, medicine and food industries. It can also be used in rubber, dyes, semiconductors and military and national defense industries.

2. Used as an anti-manic drug. As an additive of enamel glass, it can increase the smoothness of enamel, reduce the melting point, and enhance the acid resistance, cold shock resistance and heat shock resistance of enamel. In the manufacture of picture tube, it can improve the stability of picture tube, increase the intensity and clarity, and reduce the surface roughness. It is also used in the manufacture of other lithium compounds, phosphors and electrolytic aluminium industry.

3. Used as spectroscopic reagent and catalyst. It is used in the preparation of lithium salts, pharmaceuticals, ceramics and glass industry.

4. Used as an electrolytic additive in aluminium smelting and in electroplating treatment.
