Silica Powder is a natural quartz (SiO2) or fused silica (natural quartz at high temperature melting, after cooling the amorphous SiO2) by crushing, milling (or vibration, jet mill), classification, flotation, acid purification, high water processing multi-channel processing by the oxide silicon powder.
Silica is a non-toxic, tasteless, non-polluting inorganic non-metallic materials.
As the silica Powder or silica flour which has good heat resistance, acid and alkali resistance, poor thermal conductivity, high insulation, low thermal expansion, chemical stability, hardness and other excellent performance, so silica powder is widely used in chemical, electronics, integrated circuit (IC) , electrical appliances, plastics, coatings, advanced paint, rubber, defense and other fields. |
