Lithium carbonate produced from lepidolite is commonly used in people's lives. It is an environmentally friendly and pollution-free new energy source. It is often used in the following fields.
1. Glass manufacturing field
Lithium carbonate is mainly used in the production process of cathode picture tubes, heat-resistant glass, glass fibers and optical glass. It can not only reduce the maturation and melting temperature of glass, increase the density and strength of glass, but also improve many important properties such as the viscosity and thermal expansion of glass.
2. Application in the field of ceramics
In the ceramic manufacturing process, adding an appropriate amount of lithium carbonate can not only increase the transparency and wear resistance of the product, but also reduce the expansion coefficient and melting temperature, thereby reducing fuel consumption and extending furnace life.
3. Application in the medical field
In the medical field, lithium carbonate can be used as a sleeping pill and sedative, and can also be used to treat anorexia nervosa, pathological hypersexuality, spastic torticollis, joint inflammation, epilepsy, etc., and has become the drug of choice for the treatment of mania.
4. Non-ferrous metal smelting field
In the aluminum smelting industry, using carbonaceous materials containing 0.4 to 1.5 lithium carbonate instead of ordinary activated carbon materials as anodes can reduce the anode's The overpotential is reduced by 150~200mV, and 300~600 kW·h of electricity can be saved per ton of aluminum produced.
5. Lithium battery electrode materials
Lithium carbonate is the most important product among lithium compounds. It can be used as the basic raw material to produce various lithium compounds. At present, as the cathode material of lithium-ion batteries, high-purity lithium carbonate used in the electrolyte has attracted more and more attention. It is the main raw material for producing metals such as Li, LiOH, LiBr, etc. It is not only used in lithium-ion batteries, but also in surface elastic wave element materials lithium tantalate and lithium niobate.
