1.Introduction :
Silicon metal is produced in the electric-arc furnace by the reduction of silica by a carbonaceous reducing agent yielding silicon metal and carbon monoxide gas. Such carbonaceous materials as coke, coal, and wood chip are used.
2.Application:
1. In metallurgy and foundry line, industrial silicon powder is regarded as to be iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel hardenability.
2. Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance. Products made of it are applied in steel smelting furnace, kiln hood and kiln furniture etc.
3. In the chemical line of organic silicon, industrial silicon powder is basic raw material that high polymer of organic silicon formatting. Such as using for producing organic monomer, silicon oil, silicon rubber antiseptic to improve the characteristics of insulating, corrosion-resistance and waterproof performance etc.
4. Industrial silicon powder is sublimated into polysilicon, which is widely used in hi-tech field as an essential raw material for integrated circuit,semiconductor and electronic element.
