Description

A colloidal form of Silica that is a very light, fluffy white powder. Aerosol silica, also called fumed silica, is made by hydrogen-oxygen furnace combustion of silicon tetrachloride. This produces tiny spherical particles of varying sizes. Aerosol 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.

Synonyms and Related Terms

fumed silica; Aerosil® [Degussa-Huls]; Cab-O-Sil [Cabot]

Risks

Inhalation may cause silicosis; Use dust mask.
CDH (Fumed silica): SDS

Physical and Chemical Properties

CAS = 112945-52-5
