White carbon black is white powder X-ray amorphous silicate products and the floorboard of the silicate, is mainly refers to precipitate silica, gas phase silica, ultrafine silicon gel and gel, also including powder synthesis of aluminium ailicate and calcium silicate, etc. Silica is porous material, its composition can be used nH2O said, among them, SiO2 is nH2O surface hydroxyl exists in the form of. Soluble in treatments and hydrofluoric acid, insoluble in water, solvents and acid (hydrofluoric acid except). High temperature resistant, non-flammable, tasteless, odorless, has the very good electrical insulation.
