Silicon powder is made of natural quartz or fused quartz by crushing, ball milling (or vibration, air grinding), 

flotation, pickling purification, high purity water treatment and other processes. Silicon powder is a non - toxic, 

tasteless, non - polluting inorganic non - metallic raw material. Because it has good temperature resistance, acid 

and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical propert

-ies, high hardness and other excellent performance, is widely used in chemical industry, electronics, integrated 

circuit (IC), electrical appliances, plastics, coatings, advanced paint, rubber, national defense and other fields. 

With the rapid development of high technology field, silicon powder will enter a new historical development period.
