Requirements for silicon micro powder indicators, industry status, market and development trends!

Silicon micropowder is a kind of inorganic non-metallic mineral functional powder material, which is made from natural quartz ore, fused silica and other raw materials through color separation, acid leaching, flotation, magnetic separation, grinding, precision classification and other fine processing. It is widely used in electronic materials, electrical insulation materials, adhesives, special ceramics, precision casting, paint coatings, ink, silicone rubber, functional rubber, advanced building materials and other fields.

1. Classification and Physical and Chemical Performance Index Requirements for Silicon Micropowder

SJ/T 10675-2002 "Silicon Dioxide Micropowder for Electronic and Electrical Industry" divides silicon micropowder into ordinary silicon micropowder, ordinary active silicon micropowder, electrical grade silicon micropowder, electrical grade crystalline silicon micropowder, electronic grade crystalline active silicon micropowder, electronic grade molten silicon micropowder, and electronic grade molten active silicon micropowder.

2. The current situation of the silicon micro powder industry

At present, the silicon micro powder produced in China is mainly composed of ordinary angular crystalline silicon micro powder and angular molten silicon micro powder. The mid to high end silicon micro powder products represented by square quartz powder, spherical silicon micro powder, ultrafine silicon micro powder, etc. are still mainly produced by enterprises in developed countries such as Japan and the United States.
