        What is silicon metal?

        Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive to non-ferrous based alloys. Si metal is a product obtained by smelting quartz and coke in an electric furnace. The main content is silicon element with above 99%, and the remaining impurities are iron, aluminum, calcium etc.


        Use of silicon metal

        It is mainly used In the aluminum alloy industry. Silicon-aluminum alloy is a strong composite deoxidizer. In the process of steel making, replacing pure aluminum can improve the utilization rate of deoxidizer, and can purify molten steel and improve the quality of steel. Industrial silicon is also used as an alloying agent for demanding silicon steel, smelting special steel and non-ferrous based alloy deoxidizer.


        It is also used to produce silicone rubber, silicone resin, silicone oil and other silicones in the chemistry industry. Silicone rubber has good elasticity, high temperature resistance, used in the manufacture of medical supplies, high temperature gaskets. Silicone is used in the production of insulating varnishes, high temperature coatings, etc. Silicone oil is an oil whose viscosity is little affected by temperature. It is used to produce advanced lubricants, polishes, fluid springs, dielectric liquids, etc. It can also be processed into a colorless and transparent liquid, which is sprayed as a high-grade waterproofing agent on the surface of the building.


        Industrial silicon is purified by a series of processes to produce polycrystalline silicon and monocrystalline silicon for use in the photovoltaic industry and the electronics industry. Crystalline silicon cells are mainly used in solar roof power stations, commercial power stations and high-cost urban power stations. They are the most mature and widely used solar photovoltaic products, occupying more than 80% of the world PV market, and their demand for siliocn metal is great. Modern large-scale integrated circuits are almost always made of high-purity metal silicon, and high-purity metal silicon is also the main raw material for producing optical fibers. It can be said that silicon matal has become the basic pillar industry in the information age.
