Silicon metal can effectively improve the high temperature resistance, wear resistance and oxidation resistance of products. It is widely used in steelmaking furnaces. silicon Metal is also used in the silicone chemical industry, for the production of silicon monomer, silicone oil, silicone rubber preservatives, so as to improve the product's high temperature resistance, electrical insulation, corrosion resistance, corrosion resistance, waterproof and others . At the same time, through the purification process of silicon metal, monocrystalline silicon is produced, which can be widely used in integrated circuits and electronic components. In the metallurgical and casting industry, silicon metal is used as a non-ferrous alloy additive and silicon steel alloy agent, thus improving the hardenability of steel.
