Silicon fine powder

Silica is an extremely versatile class of inorganic non-metallic material with excellent dielectric properties, low coefficient of thermal expansion, high thermal conductivity, silica powder quartz powder products and their ingredients by advanced ultra-fine grinding process by the processed . It has high brightness, fine particles, particle size distribution reasonably large specific surface area, excellent suspension properties, higher purity of the advantages of
Widely used in friction materials, coatings, paints, adhesives, silicone rubber, precision casting, high-grade ceramic, epoxy resin casting materials and general electronics, high voltage insulation components casting, molding compounds and IC encapsulation material, powder coating, protective layer welding, and other resin fillers.
Silica powder was gray, spherical particles, fine, fine particles smaller than most 0.01UM, the average particle size of 0.1-0.3UM, room temperature, easy to integrate into loose block, gelation and high adsorption capacity, widely used in friction materials, refractories, roads, bridges, tunnels, chemical ceramic, rubber and other industries.
