Description
A colloidal form of silica that is a very light, fluffy white powder. Fumed silica, also called aerosol silica, is made by hydrogen-oxygen furnace combustion of silicon tetrachloride. This produces tiny spherical particles of varying sizes. Fumed silica is available in hydrophilic and hydrophobic (coated) forms. It is used as a matting agent, thickener, and filler in many adhesives and coatings. Fumed silica has also been used as a desiccating agent to kill insects.
