Silica Sand

 

Silicon dioxide, also known as silica (from the Latin silex), is a

 chemical compound that is an oxide of silicon with the chemical formula SiO2. It has been known since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms (frustule).

 

Silica is manufactured in several forms including fused quartzcrystalfumed silica (or pyrogenic silica), colloidal silicasilica gel, and aerogel.

Silica is used primarily in the production of glass for windows, drinking glasses, beverage bottles, and many other uses. The majority of optical fibers fortelecommunications are also made from silica. It is a primary raw material for many ceramics such as earthenwarestoneware, and porcelain.

 

Silica is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications. It is the primary component of diatomaceous earth, which has many uses ranging from filtration to insect control. It is also the primary component of rice husk ash, which is used, for example, in filtration and cement manufacturing.
