Lithium carbonate is an inorganic compound, chemical formula Li2CO3, molecular weight 73.89, colorless monoclinic crystal, slightly soluble in water and dilute acid, insoluble in ethanol and acetone. The thermal stability is lower than the carbonates of other elements in the same group in the periodic table, and it does not deliquesce in the air. It can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solution. It can be converted into acid salt by introducing carbon dioxide into its aqueous solution, which can be hydrolyzed by boiling. It is used as raw materials for ceramics, glass, ferrite, etc., and components are sprayed with silver paste. It is used in medicine to treat mental depression.
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.Battery grade lithium carbonate is mainly used for the preparation of lithium cobalt oxide, lithium manganese oxide, ternary materials, lithium iron phosphate and other lithium ion battery cathode materials .
Lithium carbonate, an inorganic compound with the chemical formula Li2CO3, is a colorless monoclinic crystal or white powder. Density 2.11g/cm3. Melting point 723℃ (1.013*10^5Pa). Soluble in dilute acid. Slightly soluble in water, the solubility in cold water is greater than that in hot water. Insoluble in alcohol and acetone. It can be used to make ceramics, medicines, catalysts, etc. Commonly used raw materials for lithium-ion batteries.
Function and use
Used to prepare various lithium compounds, metallic lithium and its isotopes. Also used to prepare catalysts for chemical reactions. There are also applications in the semiconductor, ceramics, television, pharmaceutical and atomic energy industries. Used as analytical reagents in analytical chemistry. It also has applications in lithium-ion batteries. Used as a setting accelerator in cement admixtures.
Lithium carbonate has a significant inhibitory effect on mania and can improve the affective disorders of schizophrenia. It has no effect on the mental activities of normal people at a therapeutic dose. The mechanism of action may be related to inhibiting the release of norepinephrine at synapses in the brain and promoting regeneration. Ingested, it has an effect on increasing peripheral blood cells. Small doses of this medicine are used to treat uterine fibroids combined with menorrhagia. Small doses can also be used for acute bacillary dysentery. Lithium salts have no sedative effect and are generally used for severe acute mania. The patient was first treated with chlorpromazine or haloperidine, and then maintained with lithium carbonate alone after acute symptoms were controlled.
Function and usage: Industrial grade lithium carbonate is mainly used in steel continuous casting mold slag; in the electrolytic aluminum industry, adding industrial grade lithium carbonate can reduce the volatility, viscosity and melting point of the electrolyte, and improve the conductivity of the electrolyte, thereby reducing heat loss and improving Current efficiency, energy saving and prolonging the service life of electrolytic cells; used to prepare refrigerant lithium bromide; used to prepare lithium chloride as a raw material for metal lithium electrolysis; used to prepare high-purity grade lithium carbonate and pharmaceutical grade lithium carbonate; Used in glass, ceramics, enamel and enamel, etc.
Storage and use: Avoid contact with eyes, skin and clothes; keep away from strong acids and strong oxidizing substances, and store in a ventilated, dry and airtight manner.
Packing: paper-plastic composite bag lined with 2 layers of PE bag, 25kg/bag or as customer's request.
Shipping: The product is not classified as a hazardous chemical and is suitable for shipping by sea, rail, air and road. Pay attention to moisture-proof and acid-proof during transportation.
