The application of silicon metal

The uses of metal silicon include: production of silicone rubber, production of silicone resin, production of silicone oil, production of high-purity semiconductors, and preparation of alloys.
1. Silicone rubber
Silicone rubber has good elasticity and high temperature resistance, and is used to make medical supplies, high temperature resistant gaskets, etc.
2. Silicone resin
Silicone resin is used in the production of insulating varnishes, high-temperature coatings, etc.
3. Silicone oil
Silicone oil is an oily substance whose viscosity is little affected by temperature. It is used to produce high-grade lubricants, glazing agents, fluid springs, dielectric liquids, etc. It can also be processed into colorless and transparent liquids and sprayed as high-grade waterproofing agents. on the surface of buildings.
4. Manufacture of high-purity semiconductors
Almost all modern large-scale integrated circuits are made of high-purity metal silicon, and high-purity metal silicon is also the main raw material for the production of optical fibers. It can be said that metal silicon has become the basic pillar industry of the information age.
5. Alloy preparation
Silicon-aluminum alloy is the most used silicon alloy. Silicon-aluminum alloy is a strong composite deoxidizer, which can improve the utilization rate of deoxidizer when replacing pure aluminum in the steelmaking process, and can purify molten steel and improve steel quality. Silicon-aluminum alloy has low density, low thermal expansion coefficient, good casting performance and wear resistance. The alloy castings cast with it have high impact resistance and good high-pressure compactness, which can greatly improve the service life. It is often used to produce aerospace vehicles and auto parts.
