Silicon(IV) oxide, 99.99% (metals basis)

Description

CAS: 7631-86-9 | O2Si | 60.08 g/mol

Silica is used primarily in the production of glass for windows, drinking glasses, beverage bottles. The majority of optical fibers for telecommunication are also made from silica. It is a primary raw material for many ceramics such as earthenware, stoneware, and porcelain. The main ingredient in sand casting for the manufacture of a large number of metallic components in engineering and other applications. Silica is a common additive in the production of foods. An estimated 95% of silicon dioxide produced is consumed in the construction industry.
