(1) Production of silicone rubber, silicone resin, silicone oil and other organic silicon
Silicone rubber has good elasticity and high temperature resistance, and is used to make medical supplies, high temperature gaskets, etc
Silicone resin is used in the production of insulation paint, high-temperature coatings, etc
Silicone oil is an oily substance whose viscosity is minimally affected by temperature. It is used in the production of advanced lubricants, polishes, fluid springs, dielectric liquids, etc. It can also be processed into a colorless and transparent liquid and sprayed as an advanced waterproofing agent on building surfaces
(2) Manufacturing high-purity semiconductors
Modern large-scale integrated circuits are almost all made of high-purity metal silicon, which is also the main raw material for producing optical fibers. It can be said that metal silicon has become the basic pillar industry of the information age
(3) Prepare alloy
Silicon aluminum alloy is the most widely used silicon alloy Silicon aluminum alloy is a strong composite deoxidizer that can replace pure aluminum in steelmaking processes to improve the utilization rate of deoxidizers, purify molten steel, and improve steel quality Silicon aluminum alloy has low density, low coefficient of thermal expansion, good casting performance and wear resistance. The alloy castings cast with it have high impact resistance and good high-pressure density, which can greatly improve the service life. It is commonly used in the production of aerospace and automotive parts
Silicon copper alloy has good welding performance and is not prone to sparking when subjected to impact. It has explosion-proof function and can be used to make storage tanks
Adding silicon to steel to make silicon steel sheets can greatly improve the magnetic conductivity of steel, reduce hysteresis and eddy current losses, and can be used to manufacture iron cores for transformers and motors, improving their performance.
The main production areas of metallic silicon are Yunnan, Sichuan, Guizhou, and Guangxi in southwestern China, Hunan and Hubei in central China, Fujian in eastern China, Heihe and Linjiang in Heilongjiang, Jilin and Liaoning in northeastern China, as well as Inner Mongolia.
