Pyrogenic or fumed silica is silica prepared by the combustion of a volatile silicon compound (usually SiCl(4)). Precipitated silica is silica precipitated from an aqueous solution. Colloidal silica is a stable dispersion of discrete, colloid-sized particles of amorphous silica in an aqueous solution. /Amorphous forms/
