What is lithium carbonate and its classification and use?

(1) What is lithium carbonate？

  Lithium carbonate is an inorganic compound with the chemical formula Li2CO3, molecular weight 73.89, colorless monoclinic crystal, slightly soluble in water and dilute acids, 

insoluble in ethanol and acetone. Carbonates with lower thermal stability than other elements of the same group in the periodic table and do not deliquescence in air 

can be obtained by adding sodium carbonate to a solution of lithium sulfate or lithium oxide. Widely used in fields such as batteries, glass, ceramic coatings, etc.

(2) Lithium carbonate classification:

  Lithium carbonate can be divided into industrial grade lithium carbonate (with a lithium carbonate content of 98% -99%)

  And battery grade lithium carbonate (lithium carbonate content ≥ 99.5%)

(3) Lithium carbonate usage:

      Lithium carbonate can be used in the manufacturing of lithium compounds, enamel, and glass. It is a raw material for producing lithium compounds and metallic lithium, 

and can be used as an electrolytic bath additive in aluminum smelting. Widely used in industries such as glass, ceramics, etc.

    Battery grade lithium carbonate is mainly used to prepare lithium-ion battery cathode materials such as lithium cobalt oxide, lithium manganese oxide, ternary materials, and 

lithium iron phosphate.

     High purity lithium carbonate is mainly used in the preparation of high-end lithium-ion battery cathode materials and battery grade lithium fluoride; In terms of 

optoelectronic information, high-purity lithium carbonate is used to prepare lithium tantalate and lithium niobate.
