Silicon(IV) oxide, microcrystalline

Description

CAS: 14808-60-7 | O2Si | 60.08 g/mol

In the manufacture of glass, ceramics and abrasives, in water filtration, in cosmetics, pharmaceuticals and rubber, as a thermal insulatorSilica is used in the manufacture of glass for windows, drinking glasses, beverage bottles, and many other materials. Optical fibers for telecommunication are made from silica. It is also used as a raw material for many ceramics such as earthenware, stoneware, and porcelain. In addition, silica is a common additive in the production of foods and pharmaceutical products.
