English name: Carbon balck
Silica is a white powder X-ray amorphous silica and silicates, collectively, mainly refers to precipitated silica, fumed silica, fine silica gel and Aerogel, including powder synthesis aluminum and calcium and so on. Silica is a porous material, its composition can be SiO2 nH2O said one nH2O is in the form of surface hydroxyl groups. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, flammable, tasteless, odorless, has very good electrical insulation.
