How much do you know about lithium carbonate?
Synthesis methods of Lithium carbonate
1. Brine comprehensive utilization method: brine after the extraction of barium chloride lithium-containing material liquid, add soda ash to remove calcium, and magnesium ions in the material liquid, add hydrochloric acid acidification, evaporation to remove sodium chloride, and then remove iron, then add excess soda ash to make lithium carbonate precipitation, after washing, centrifugal separation, drying, to produce lithium carbonate finished products.
2. Lime sintering method: Lithium pyroxene concentrate (generally containing 6% lithium oxide) and limestone are dosed in a 1:(2.5-3) weight ratio. Mixed and ground, sintered at 1150 ~ 1250 ℃ to generate lithium aluminate and calcium silicate, crushed by wet grinding, leaching lithium hydroxide with washing solution, filtered by settling, the filter residue returned or washing to remove slag, leaching solution by evaporation and concentration, then add sodium carbonate to generate lithium carbonate, and then separated by centrifugation, drying, to produce lithium carbonate finished products.
3. High-purity lithium carbonate can be produced by reacting lithium hydroxide with carbon dioxide, or lithium sulfate and sodium carbonate can be used as reactants. Still, lithium carbonate is easily soluble in other salt solutions, so the yield is not very high, generally about 75%, and the product will also contain a small amount of lithium sulfate.
4. Sulphuric acid method: reacting molten lithium pyroxene with sulphuric acid, purified, and then reacting with sodium carbonate.
5. Lime method: reacting roasted lithium pyroxene with lime milk, purified and then reacting with sodium carbonate.
6. By-product method: Extracted from the mother liquor containing lithium after producing barium chloride from well salt brine.
7. Industrial lithium hydroxide as raw material, heated water to dissolve it, filter out the insoluble matter while hot to the filtrate into the clean carbon dioxide gas until no longer generated precipitation, while hot filter, shake dry, wash with hot distilled water to pass, at 110 ℃ drying can be. Industrial lithium carbonate dissolved in cold water, filtered, filtrate boiled, stopped heating, and filtered while hot water washing, shaking dry, drying, can also be reagent lithium carbonate.
What is Lithium carbonate used for?
1. Lithium carbonate is used in the manufacture of lithium compounds and enamels, glass, as a raw material for the production of lithium compounds and lithium metal, and as an additive in the electrolytic bath of aluminum smelting. It is widely used in the glass, ceramics, pharmaceutical, and food industries, as well as in synthetic rubber, dyes, semiconductors, the military defense industry, television sets, atomic energy, medicine, and catalysts. It is used to produce acoustic and optical-grade single crystals. It is also used in treating psychotic disorders and as a sedative.
2. Battery-grade lithium carbonate is mainly used to prepare lithium cobaltate, manganate, ternary materials, lithium iron phosphate, and other lithium-ion battery cathode materials.
3. High-purity grade lithium carbonate is mainly used in the preparation of high-end lithium-ion battery cathode materials and the preparation of battery-grade lithium fluoride; in optoelectronic information, high-purity grade lithium carbonate is used in the preparation of lithium tantalate and lithium niobate; at the same time, high-purity grade lithium carbonate is also used in a special optical glass, magnetic materials industry, and supercapacitors, pharmaceutical industry, etc.
Price of Lithium carbonate
Particle size and purity will affect the product's price, and the purchase volume can also affect the cost of particle size. A large amount of large amount will be lower. The price of particle size can be found on our company's official website.
