Silica is a white powder X- ray amorphous silicic acid and silicate products collectively, mainly refers to precipitated silica, fumed silica and ultrafine silica gels, including powdered synthetic silicic acid aluminum and calcium silicate. Silica is a porous material, the composition can be used SiO2 · nH2O, where nH2O in the form of surface hydroxyl groups present. Soluble in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, flammable, tasteless, odorless, and has good electrical insulation.
