Silicon powder is an odorless, non-polluting inorganic non-metallic material。Because it has good temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion, chemical stability, high hardness and other excellent performance, is widely used in chemical industry, electronics, integrated circuit (IC), electrical appliances, plastics, coatings, high paint, rubber, national defense and other fields。With the rapid development of high-tech fields, silicon powder will also enter a new historical development period。
Silicon powder is made of natural quartz (SiO2) or molten quartz (amorphous SiO2 after high temperature melting and cooling of natural quartz) by crushing, ball milling (or vibration, air grinding), flotation, pickling purification, high purity water treatment and other processes。
