What are the main uses of lithium carbonate?

Physical properties of lithium carbonate: melting point 723°C, boiling point 1342°C, relative density 2.11g/cm3, water solubility 13g/L (20°C). It is not easy to oxidize and deliquesce in the air, and has good thermal stability. It can be stored at room temperature, but it has strict requirements on humidity and needs to be kept in a dry environment. The solubility in water is very small, and the solubility decreases with the increase of temperature.

Chemical properties of lithium carbonate: When heated to the boiling point, it begins to partially decompose into lithium oxide and carbon dioxide (Li2CO3 = heating = Li2O + CO2); soluble in dilute acid (Li2CO3+ 2H+ =2Li+ + H2O + CO2), insoluble in alcohol (ethanol, acetone) . Chemically stable, durable in storage and easy to transport.

Lithium carbonate is an important lithium chemical raw material. Its main uses include:

Lithium-ion battery: Lithium carbonate is an important raw material for manufacturing lithium-ion batteries, which is used in the battery manufacturing of electronic equipment such as mobile phones, laptops, and electric vehicles.

Ceramics and glass industry: Lithium carbonate can be used to make special glasses and ceramics, such as crystal glass, colored glaze and ceramic glazes.

Pharmaceutical industry: Lithium carbonate can be used to make certain drugs, such as those to treat bipolar disorder and depression.

Metallurgical industry: Lithium carbonate can be used as an additive in aluminum and magnesium alloys to improve the properties of the alloys.

Other uses: Lithium carbonate can also be used in the production of chemical products such as synthetic lubricants, coatings, and plastic additives.
