How is silica micro powder 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 chemical, electronic, integrated circuit (IC), electrical, plastic, coating, advanced paint, rubber, national defense and other fields.

1. Classified by level, silicon micro powder can be divided into ordinary (ultrafine) silicon micro powder, electrical and electronic grade silicon micro powder, molten silicon micro powder, and spherical silicon micro powder.

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

3. The production process can be divided into: crystalline silica micro powder, fused silica micro powder, quartz silica micro powder, and activated silica micro powder.
