1, metal silicon can produce silicone rubber, silicone resin, silicone oil and other silicones. Silicon metal production of silicone rubber elasticity, high temperature resistance, used in the manufacture of medical supplies, high temperature gaskets and so on. Silicone resin is used in the production of insulating coatings, high-temperature coatings and so on. Silicone oil is an oil, its viscosity is little affected by temperature, used in the production of lubricants, optical agents, fluid springs, dielectric fluid, etc., can also be processed into a colorless and transparent liquid, as a waterproofing agent coated on the surface of the building.
2, the manufacture of high-purity semiconductors. Modern large-scale integrated circuits are almost all made of high-purity silicon metal, high-purity silicon metal is the main raw material for optical fiber production. It can be said that silicon metal has become the basic pillar industry of the information age.
3, the preparation of alloys. Silicon aluminum alloy is a strong compound deoxidizer. In the steelmaking process, replacing pure aluminum can improve the utilization rate of the deoxidizer, purify the molten steel and improve the quality of steel. Silicon aluminum alloy density is small, low coefficient of thermal expansion, casting performance and wear resistance. Casting alloy casting high impact resistance, high pressure densification, can greatly improve the service life, commonly used in the production of space shuttles and automotive parts.
