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.
