How are silicon micro powders classified?

Silicon micropowder is made of natural quartz or fused silica (natural quartz is amorphous SiO2 after high temperature melting and cooling) through crushing, purification, grinding, 

grading and other processes.

Silicon micro powder has excellent properties such as good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness. It is widely used in fields such as chemical engineering, electronics, integrated circuits (ICs), electrical appliances, plastics, coatings, advanced paints, rubber, and national defense.

Divided by level, silicon micropowder can be divided into: ordinary (ultrafine) silicon micropowder, electrical and electronic grade silicon micropowder, molten silicon micropowder, and

spherical silicon micropowder.

Usage classification: Silicon powder can be divided into: silicon powder for paint coatings, silicon powder for epoxy flooring, silicon powder for rubber, silicon powder for sealant, silicon powder for electronic and electrical grade plastic sealing materials, and silicon powder for precision ceramics
