Metallic calcium is a silver-white light metal, its main raw material limestone is widely distributed and exists in the crust. There are two production methods of metallic calcium, one is the metal calcium produced by electrolysis, its purity is generally more than 98.5%, after further sublimation, can reach 99.5% purity. The other is the metal calcium produced by aluminothermic process, whose purity is generally about 97%. After further sublimation, the purity can be improved to a certain extent. In terms of physical properties, electrolytic metallic calcium is relatively soft and easy to process, and the recovery rate is relatively high. However, the metallic calcium produced by aluminothermic process is relatively hard and the loss is relatively large in the process. USE： * Desulfurization, degassing and degassing in steelmaking and cast iron. * In the production of niobium chromium titanium uranium and vanadium and other metals deoxidation process. * As an alloy used in the lead industry to produce maintenance-free car batteries, calcium lead alloys increase strength, corrosion resistance and creep resistance. * In the production of aluminum cymbals copper lead magnesium and other nonferrous alloys as alloy agent. * Used as deoxidizer in the production of high purity steel and non-ferrous metals.
