Silica is a non-toxic, tasteless, non-polluting inorganic non-metallic materials

Silica is a natural quartz or fused silica (high temperature melting natural quartz, amorphous after cooling) by crushing, milling (or vibration, jet mill), flotation, acid purification,  Diamond blade  water and other multi-channel processing technology into a fine powder. Silica is a non-toxic, tasteless, non-polluting inorganic  cubic boron nitride  materials.  Abrasive grinding wheel  good heat resistance, acid corrosion, poor thermal conductivity, high insulation, low thermal expansion,
Chemical stability, hardness, and other excellent properties, is widely used in chemical, electronics, integrated circuits, electrical appliances, plastics, coatings, advanced paint, rubber, defense and other fields.
