Lithium carbonate (molecular structure is Li2CO3, English name is lithium carbonate) as a colorless monoclinic crystal or white powder. Density is 2.11. Melting point is 618 ℃. Without deliquescence, it is stable in the air. Low solubility in water, the solubility decreases with increasing temperature. Solubility in cold water is greater than hot water. It is Soluble in dilute acid, insoluble in alcohol and acetone. Carbon dioxide is introduced into the aqueous suspension of lithium carbonate, lithium carbonate is converted to lithium acid carbonate and dissolved. If the solution of lithium acid carbonate is heated and then it releases carbon dioxide and precipitates lithium carbonate. The nature of the lithium carbonate may be used to remove impurities from lithium carbonate. Since lithium ion has a strong polarizability, thus thermal stability of lithium carbonate is worse than other alkali metal carbonate, when heated to above the melting point, it will decompose to produce carbon dioxide and lithium oxide.

The lithium carbonate industry is a global high monopoly industry, the current production capacity is mainly concentrated in three foreign manufacturers of SQM, FMC, Chemetall and so on.

Industrial lithium carbonate is used in the manufacture of other lithium salts, such as lithium chloride and lithium bromide and so on. It also acts as lithium oxide materials in enamel, glass, pottery and porcelain enamel, and it is also added to the electrolytic cell for electrolysis of aluminum to increase the current efficiency and reduce the internal resistance of the cell and the bath temperature. In medicine, it is mainly used for the treatment of mania, can improve their emotional disorders for schizophrenia. It has the effect of elevating peripheral leukocytes.

Uses A neuroprotective effect of lithium carbonate in amyotrophic lateral sclerosis (ALS).

General Description A white powder. Strong irritant when dissolved in water.

Air & Water Reactions Slightly soluble in water.

Reactivity Profile A base. Decomposed by acids with the evolution of carbon dioxide. Fluorine burns fiercely on contact with Lithium carbonate.
