Silicon metal (Si) is an industrial purified elemental silicon, which is mainly used in the production of organosilicon, the preparation of high-purity semiconductor materials and the preparation of alloys with special uses.
The production of silicone rubber, silicone resin, silicone oil and other silicone, silicone rubber elastic, high temperature resistance, used in the production of medical supplies, high temperature gaskets and so on. Silicone resin is used in the production of insulating paint, high temperature coatings and so on. Silicone oil is a kind of oil, its viscosity is very little affected by temperature, used for the production of advanced lubricants, glazing agents, fluid springs, dielectric liquids, etc., can also be processed into colorless transparent liquid, as an advanced waterproof agent sprayed on the surface of buildings.
Manufacturing high-purity semiconductors, modern large-scale integrated circuits are almost all made of high-purity metal silicon, and high-purity metal silicon is the main raw material for the production of optical fiber, it can be said that metal silicon has become the information age basic pillar industry.
Alloy preparation, silicon aluminum alloy is the largest amount of silicon alloy. Silicon aluminum alloy is a strong composite deoxidizer, in the steelmaking process instead of pure aluminum can improve the utilization rate of deoxidizer, and can purify liquid steel, improve the quality of steel silicon aluminum alloy density is small, low coefficient of thermal expansion, casting performance and wear resistance is good, with its casting alloy castings have a high impact resistance and good high pressure compactness, can greatly improve the service life. It is commonly used in the production of aerospace vehicles and auto parts. Silicon copper alloy has good welding performance, and is not easy to produce sparks when impacted, with explosion-proof function, can be used to make storage tanks.
