Silicon(IV) oxide is used in a variety of applications such as manufacturing of glass, ceramics and abrasives, and water filtration. It is a common additive in dentifrice oral care applications and the production of foods, where it is used primarily as an anti-caking and free-flow agent in powdered foods, or to absorb water in hygroscopic applications.

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. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
