Silicon Metal Powder

Metal silicon powder use

1. Industrial silicon powder is widely used in refractory materials and powder metallurgy industries to improve the high temperature resistance, wear resistance and oxidation resistance of products. Its products are widely used in steelmaking furnaces, kilns and kiln furniture.

2. In the organosilicon chemical industry, industrial silicon powder is the basic raw material for organosilicon polymer synthesis, such as the production of silicon monomers, silicone oil, and silicone rubber preservatives, thereby improving the product's high temperature resistance, electrical insulation, and corrosion resistance. properties, anti-corrosion, waterproof and so on.

3. Industrial silicon powder is drawn into monocrystalline silicon, and the processed silicon wafer is widely used in high-tech fields and is an indispensable raw material for integrated circuits and electronic components.

4. In the metallurgical casting industry, industrial silicon powder is used as a non-ferrous alloy additive and a silicon steel alloy agent to improve the hardenability of steel. Industrial silicon powder can also be used as a
reducing agent for certain metals, for new ceramic alloys, etc.
