Lithinm Carbonate,Bingsheng Chemical,Gypsum

Lithium carbonate is colorless monoclinic crystal or white powder. Density 2.11, melting point 618℃. No deliquescence, is stable in air. The solubility in water is very small, and the solubility decreases with the increase of temperature. The solubility in cold water is larger than that in hot water. Soluble in dilute acid, insoluble in ethanol and acetone. When carbon dioxide is passed into the aqueous suspension of lithium carbonate, lithium carbonate is transformed into lithium carbonate acid and dissolved. If the solution of lithium carbonate acid is heated, carbon dioxide is released and lithium carbonate is precipitated.

  • Molecular weight 73.89
  • CAS NO. 554-13-2
  • HS CODE 28369100

GENERAL DESCRIPTION

Lithium carbonate is colorless monoclinic crystal or white powder. Density 2.11, melting point 618℃. No deliquescence, is stable in air. The solubility in water is very small, and the solubility decreases with the increase of temperature. The solubility in cold water is larger than that in hot water. Soluble in dilute acid, insoluble in ethanol and acetone. When carbon dioxide is passed into the aqueous suspension of lithium carbonate, lithium carbonate is transformed into lithium carbonate acid and dissolved. If the solution of lithium carbonate acid is heated, carbon dioxide is released and lithium carbonate is precipitated. This property of lithium carbonate can be used to remove impurities. Since lithium ions are highly polarized, due to Chemicalbook this lithium carbonate is somewhat less thermally stable than other alkali metal carbonates, and when heated above its melting point, decomposition occurs, producing lithium oxide and carbon dioxide. Industrially lithium carbonate is used to make other lithium salts such as lithium chloride and lithium bromide. It is also used as a raw material for lithium oxide in enamel, glass, ceramics and porcelain enamel, and is also added to the electrolysis of aluminum electrolysis tanks to increase current efficiency and reduce the internal resistance of the electrolysis tank and tank temperature. In medicine, it is mainly used in the treatment of mania, and can improve the emotional disorder of schizophrenia. It has the effect of elevating peripheral white blood cells.
