Silicon dioxide is used to manufacture glass ceramics and cement. It is used in the electronics industry to produce semiconductor chips and insulating layers. Silicon dioxide is added to foods as an anti-caking agent to prevent powders from clumping. It is used as a raw material in the production of concrete and other construction materials. Silicon dioxide is used in toothpaste as a mild abrasive to help clean teeth.

The main purpose of silicon dioxide is to provide hardness strength heat resistance and chemical stability in a wide variety of natural and manufactured materials.

Silicon dioxide also known as silica is a naturally occurring compound made of silicon and oxygen and is one of the most abundant minerals in the Earths crust.
