Applications:
1, industrial silicon powder is widely used in refractory material, powder metallurgy industry,
in order to improve the high temperature resistance, oxidation resistance and wear loss.
Its products are widely used in steel furnace, kiln, kiln.
2, industrial silicon is the basic material of organic silicon polymer synthesis in the organic
chemical industry, such as for the production of silicon monomer, silicone oil, silicone rubber
preservatives, so as to improve the product heat resistance, electrical insulation, corrosion resistance,
corrosion resistance, waterproof and other characteristics.
3, industrial silicon powder made of single crystal silicon wafer processing by pulling, and is
widely used in the field of high technology, integrated circuit, electronic components essential raw materials.
4, metallurgy and foundry industry, industrial silicon powder as non ferrous alloy additives, silicon
steel alloy agent, so as to improve the hardenability of steel. The reducing agent of industrial silicon
can also be applied to certain metal, a new type of ceramic alloy etc..
