Silica is a white powder X- ray amorphous silica and silicates in general, mainly refers to precipitated silica, fumed silica, ultra-fine silica gel and silica airgel, white carbon black manufacturers, including powdered synthetic aluminum silicate and calcium silicate. Silica is a porous material, the composition can be used SiO2 · nH2O, where nH2O exists in the form of surface hydroxyl groups. Can be dissolved in caustic soda and hydrofluoric acid, the quality of white carbon black, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, non-flammable, tasteless, odorless, has good electrical insulation properties. Mainly used as rubber reinforcing agent and filler, silica, rubber consumption is about half of its consumption of carbon black rubber total of 94% of carbon black, white carbon black company, of which about 60% by in tire manufacturing. In addition, as inks, paints and plastics and plastics colorants UV shielding agent. In many other products, such as electrodes, batteries, resistors, explosives, cosmetics and polishing paste, it is also important additives.
