Dust Collection for Fumed Silica


Fumed silica is an artificial substance, so it’s no surprise that it’s known by multiple names—Diatomaceous earth, Diatomaceous silica, Diatomite, Silicon dioxide (amorphous), and Vitreous silica, at least. In fact, before 1989, its official name was silica (amorphous). Today, however, industry and regulators tend to call the substance fumed silica—not to be confused with silica fume, which is an industrial byproduct quite different from fumed silica. Fumed silica is a beneficial industrial chemical in many consumer and industrial products. It is made by submitting silicon tetrachloride to an intense flame, producing molten silicon dioxide spheres. These spheres then join into small, branched clusters with massive surface areas. Fumed silica’s high ratio of surface area to mass is a quality that makes the substances so valuable for many products. In particular, its effects on viscosity are profound. Fumed silica is used in paints, sealants, adhesives, cosmetics, lotions, and countless other products. The widespread use of fumed silica means it is essential to be sure it is used safely. The fine powder can quickly become airborne and, beyond a specific exposure limit, can be an inhalation hazard to workers. Fumed silica particles are microscopic and light to travel far throughout a facility. Batch mixing, equipment cleaning, and other handling are all opportunities to disturb this substance and send its dust sailing.
