What are the classifications of silica micro powder

 The classification of silicon micro powder is one kind of silicon micro powder. The ultra-fine silicon micro powder 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 has the characteristics of fine product particles, no large particles, good suspension, narrow particle size, large specific surface area, good anti sedimentation performance, and has certain reinforcement effect, as well as excellent properties such as acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, high purity and so on.

Main features:

1. The product has fine particles, no large particles, high purity, good whiteness, and uniform particle size distribution;

2. Low ion content, low conductivity, excellent electrical insulation;

3. Stable chemical properties, except for reacting with hydrofluoric acid and strong bases, it does not react with any other substances;

4. Good suspension and anti settling properties;

5. Acid and alkali resistance, high temperature resistance, and good insulation performance; Microsilica 

6. Highly wear-resistant, improving the scratch resistance of the coating.
