Application:
1. Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance. 
2. In the chemical line of organic silicon, industrial silicon powder is basic raw material that high polymer of organic silicon formatting. 
3. Industrial silicon powder is sublimated into monocrystalline silicon, which is widely used in highttech field as an essential raw material for integrated circuit and electronic element.
4. 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.
