Lithium carbonate is a Inorganic compound, chemical formula Li2CO3, molecular weight 73.89, colorless monoclinic crystal, slightly soluble in water, dilute acid, insoluble in ethanol and acetone. Carbonate with thermal stability lower than that of the same group of elements in the periodic table, which is not deliquescent in the air, can be obtained by adding sodium carbonate to Lithium sulfate or Lithium oxide solution. When carbon dioxide is introduced into its aqueous solution, it can be converted into Acid salt, and hydrolysis occurs when boiling.
Lithium carbonate can be used in the manufacture of lithium compounds, enamel and glass. It is the raw material for producing lithium compounds and metallic lithium, and can be used as an electrolytic bath additive for aluminum smelting. It is widely used in glass, ceramics, medicine, food and other industries, and can also be used in synthetic rubber, dyes, semiconductors, military Arms industry, television, atomic energy, medicine, catalysts and other aspects. Used for producing sound grade single crystals and optical grade single crystals.
Battery grade Lithium carbonate is mainly used to prepare lithium cobalate, lithium manganate, ternary materials, Lithium iron phosphate and other cathode materials for lithium ion batteries.
High purity Lithium carbonate is mainly used to prepare high-end lithium ion battery cathode materials and battery grade Lithium fluoride; In terms of photoelectric information, high-purity Lithium carbonate is used to prepare Lithium tantalate and Lithium niobate; At the same time, high-purity Lithium carbonate is also used in optical special glass, magnetic material industry, supercapacitor, pharmaceutical industry, etc.
