What are the uses of silicon metal?
When it comes to silicon metal, a lot of people don't understand! What does it do? What is the use of it? Now let me introduce the use of silicon metal.
Application of silicon metal: silicon metal (Si) is industrial purification of silicon, mainly used for the production of organosilicon, high purity semiconductor data and the production of special purpose alloys.
(1) silicon metal can be used to produce silicone rubber, silicone resin, silicone oil and other silicone
Silicone rubber has good elasticity and high temperature resistance. It is used for making medical supplies and high temperature resistance gaskets. Silicone is used to produce insulating paint, high temperature paint, etc.
Silicone oil is a kind of oil, its viscosity is affected by the temperature is very small, used for the production of high-grade lubricants, polishing agent, fluid spring, dielectric liquid, etc., can also be processed into colorless and bright liquid, as a high-grade waterproofing agent sprayed on the exterior of buildings.
2) Silicon metal can be used to make high purity semiconductors
Modern large integrated circuits are almost made of high-purity silicon metal, and high-purity silicon metal is still the primary raw material for the production of optical fiber, can be said that silicon metal has become the basic pillar industry of the information age.
(3) Silicon metal can be used to make alloys
Si-Al alloy is the most used silicon alloy. Si-Al alloy is a kind of strong compound deoxidizer, which can improve the utilization rate of deoxidizer, purify liquid steel and improve the quality of steel when replacing pure aluminum in the process of steelmaking. Silica-aluminum alloy density is small, low coefficient of thermal expansion, casting function and wear resistance function is good, the cast alloy castings with high impact resistance ability and excellent high pressure density, can greatly improve the service life, commonly used in the production of aerospace vehicles and auto parts.
The silicon copper alloy has excellent welding function, and is not easy to spark when being impacted. It has explosion-proof function, and can be used for making storage tanks.
The silicon steel sheet made of silicon in steel can greatly improve the magnetic conductivity of steel, reduce hysteresis and eddy current loss, can be used to make the core of transformer and motor, improve the function of transformer and motor. With the development of science and technology, the application of silicon metal will be further expanded.
