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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
