Superiority
Product Performance:
Silicon metal powder is also called industrial silicon powder. It is silver gray or dark gray powder with metallic luster. Of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called 'industrial glutamate', which is an essential basic raw material in hi-tech industry.
Use：
1. Industrial silica fume widely used in refractories, powder metallurgy industry, to improve the product's high temperature, wear resistance and oxidation resistance. Its products are widely used in steel-making furnaces, kilns, kiln furniture.
2. In the organic silicon chemical industry, the industrial silicon powder is the basic raw material of the organic silicon polymer synthesis, , Waterproof and other characteristics.
3. The industrial silicon powder made by the single crystal silicon, processed silicon is widely used in high-tech fields, integrated circuits, electronic components essential raw materials.
4. Metallurgical casting industry, the industrial silicon powder as a non-iron-based additives, silicon steel alloy agent, thereby enhancing the steel hardenability. Industrial silicon powder can also be applied to certain metals reductant for new ceramic alloys.
5. For the production of silica sol.
Common specifications for the 180 to 325 mesh, 200 mesh, 325 mesh, 800 mesh and so on
According to user needs to provide different particle size range.

Details
Industrial silicon powder, also known as metal silicon powder, is silver-gray or dark gray powder with metallic luster. Its high melting point, good heat resistance, high resistivity, highly resistant to oxidation, known as "industrial MSG" is a lot of high-tech industries indispensable basic raw materials.
use〕
1, industrial silicon powder is widely used in refractories, powder metallurgy industry, in order to improve the product temperature, wear resistance and oxidation resistance. Its products are widely used in steel-making furnaces, kilns, kiln furniture in.
2, in the organic silicon chemical industry, industrial silicon powder is silicone polymer synthetic base stocks, such as for the production of silicon monomer, silicone oil, silicone rubber preservatives, thereby improving product heat resistance, electrical insulation, corrosion resistance , water and other characteristics.
3, the industrial fume after drawn into silicon, silicon processing is widely used in high-tech fields, are integrated circuits, electronic components essential raw materials.
4, metallurgical foundry industry, industrial silicon powder as the non-ferrous-based alloy additives, silicon steel alloying agent to improve the steel hardenability. Industrial silicon powder may be applied to reducing certain metals for new ceramic alloys.
5, for the production of silica sol.
Common specifications for the 180 to 325 mesh, 200 mesh, 325 mesh, 800 mesh, etc.
It can provide different particle size range according to user needs.
