Product Description
Silicon metal is an important industrial product, the main component is silicon, the purity can reach more than 98%. It is reduced from quartz and coke in a submerged arc furnace and has a high melting point (1414ºC) and good physicochemical properties.
Silicon metal is used as an alloy additive in metallurgy and casting to improve the strength and wear resistance of the alloy; In silicone chemical industry, it is the basic raw material for the production of silicone oil, silicone rubber and other materials; In the high-tech sector, silicon metal is used to make monocrystalline silicon, which is a core material for semiconductor devices and solar cells.
