Property
Intoduction
Fumed silica is a highly useful industrial chemical used in a huge number of consumer and industrial products. It is made by
submitting silicon tetrachloride to intense flame, which produces molten spheres of silicon dioxide. These spheres then join
together into small, branched clusters that have a massive surface area. Fumed silica’s high ratio of surface area to mass is one
of the qualities that makes the substances so useful in so many products. In particular, its effects on viscosity are profound.
Fumed silica is used in paints, sealants, adhesives, cosmetics, lotions, and countless other products.
