Difference between industrial grade lithium carbonate and battery grade lithium carbonate
Compared with industrial grade, battery grade lithium carbonate has high purity, less impurities and good performance. Lithium carbonate is an inorganic compound. It is a colorless monoclinic crystal or white powder with the chemical formula of Li2CO3. Soluble in dilute acid, slightly soluble in water, solubility in cold water is higher than that in hot water.
Insoluble in alcohol and acetone. The density is 2.11g/cm3 and the melting point is 723 ℃. It can be used to make ceramics, drugs, catalysts, etc. and commonly used materials for lithium-ion batteries.
Compounds, metal lithium and their isotopes are used for the preparation of various lithium compounds. It is also used to prepare catalysts for chemical reactions. It is also used in semiconductor, ceramic, television, medicine and atomic energy industries. It is used as analytical reagent in analytical chemistry.
Lithium carbonate has obvious effect on depressing mania, can improve the emotional disorder of schizophrenia, and has no effect on normal people's energy activity at the dosage of treatment. The effect mechanism may be related to inhibiting the release of norepinephrine in the brain synapses and promoting reuptake, and has an effect on increasing the peripheral area cells.
Lithium aluminate was prepared by sintering spodumene and limestone at high temperature, then leaching lithium hydroxide solution and reacting with sodium carbonate. It can also be prepared by extracting barium chloride from brine, removing calcium by soda ash, acidifying with hydrochloric acid, and reacting with soda ash.
