Lithium carbonate, an inorganic compound, chemical formula Li2CO3, colorless monoclinic crystal or white powder.The density of 2.11 g/cm3.Melting point 618℃ (1.013*10^5Pa).Soluble in dilute acid.Lithium carbonate manufacturers pointed out that slightly soluble in water, in cold water solubility is larger than hot water.Insoluble in alcohol and acetone.Can be used to make ceramics, medicine, catalysts, etc.Commonly used lithium ion battery raw material.
Since the main raw material for lithium carbonate production is salt lake brine (due to the high cost of ore method, the global production capacity is very small), the large-scale production of lithium carbonate enterprises must have the exploitation right of salt lake resources with rich reserves of lithium, which makes the industry has a high resource barrier.On the other hand, since most of the global salt lake resources are high magnesium and low lithium, and it is very difficult to purify and separate lithium carbonate from high magnesium and low lithium old brine, previously these technologies were only in the hands of a few foreign companies, which made the lithium carbonate industry has technical barriers.Therefore, the lithium carbonate industry created a global oligopoly pattern.
Main uses of lithium carbonate:
1. Raw materials for lithium battery production:
In the field of high-energy lithium battery manufacturing.The specific energy of lithium carbonate battery is 3 times that of nickel hydride battery, nickel cadmium battery and 2 times that of lead acid battery.
Application in alloy manufacturing: Magnesium lithium aluminum alloy is the lighter metal structure material among the magnesium alloys studied so far, and it will have a broader application prospect in the fields of aerospace and communication.
2. Application in metallurgical industry:
Lithium is a kind of light metal, firmly combined with oxygen atoms, industrial copper, nickel process used as a deoxidizer;Lithium can be used as a sulfur cleaner;Lithium can be alloyed with a variety of metals.
3. Application in the field of medicine:
Lithium tartrate has good therapeutic effect on chronic rheumatism and acute arthritis, insane model psychosis, hyperthyroidism, chronic ulcerative colitis, Meniere’s disease and lithium-acetate diuresis.
4. Application of lubricating oil:
Industrial lithium carbonate base grease has good water resistance and good lubrication performance at high and low temperature
5. Application of ceramics:
In the glass industry it is used as a special glass with high toughness, used for ductile ceramics, metal protection ceramic coating and heat-resistant ceramic coating when it as a flux!
