What is silicon metal powder?

Silicon metal powder refers to the raw materials used in refractories and powder metallurgy industries. China's production capacity is relatively large, the output is mainly concentrated in Guizhou, Yunnan, Fujian, Guangxi, Sichuan, Hunan. Among them, metallurgical grade silicon 553 and 441 have a wide distribution area, mainly distributed in Guizhou, Hunan, Sichuan, Yunnan, Guangxi, Inner Mongolia, Xinjiang and other places, among which Guizhou is the most important production province of silicon metal powder, the output accounts for 15%-35% of the national output. The use of silicon metal powder mainly has the following aspects:

1, industrial silicon powder is widely used in refractory materials, powder metallurgy industry, in order to improve the product's high temperature resistance, wear resistance and oxidation resistance. Its products are widely used in steel-making furnaces, kilns and furnaces.

2. In the silicone chemical industry, industrial silicon powder is the basic raw material for the synthesis of silicone macromolecule, such as for the production of silicon monomer, silicone oil, silicone rubber preservative, so as to improve the high temperature resistance, electrical insulation, corrosion resistance, corrosion resistance, waterproof and other characteristics of the product.

3. Industrial silicon powder is made of monocrystalline silicon by pulling, and the silicon wafer processed is widely used in high-tech fields. It is an essential raw material for integrated circuits and electronic components.

4, metallurgical casting industry, industrial silicon powder as a non-iron base alloy additive, silicon steel alloy agent, so as to improve the hardenability of steel. Industrial silicon powder can also be used as a reducing agent for some metals, for new ceramic alloys, etc.
