The main uses of silicon metal are distinguished
1) silicon metal for the production of 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 in the production of insulating paint, high temperature paint, etc.
Silicone oil is a kind of oil, its viscosity is affected by the temperature is very small, used in the production of advanced lubricants, glazing agent, fluid springs, dielectric liquids, etc., can also be processed into a colorless and transparent liquid, as a senior waterproofing agent sprayed on the surface of buildings.
(2) silicon metal is used to manufacture high purity semiconductors
Modern large integrated circuits are almost made of high-purity silicon metal, and high-purity silicon metal is the main raw material for the production of optical fiber, silicon metal can be said to have become the basic pillar industry in the information age.
(3) silicon metal for the preparation of 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 the liquid steel and improve the quality of steel when replacing pure aluminum. Si-Al alloy has small density, low thermal expansion coefficient, good casting performance and wear resistance. The alloy castings cast with it have high impact resistance ability and good high pressure compactness, which can greatly improve the service life. It is commonly used in the production of aerospace vehicles and auto parts.
Si-Cu alloy has good welding property, and is not easy to spark when being impacted. It has explosion-proof function, and can be used to make storage tanks.
Adding silicon metal into steel to make silicon steel sheet, 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 performance of transformer and motor.
