Formation of Silicon Dioxide
Si + O2 → SiO2
Overview
Silicon reacts with oxygen to form silicon dioxide (silica), the main component of sand and quartz. This is one of the most abundant reactions on Earth's surface, as silicon dioxide makes up a large fraction of the Earth's crust.

Everyday Example
Sand on beaches and the quartz in many decorative stones are composed of silicon dioxide formed by this type of reaction.
Industrial Importance
Silicon dioxide is essential for glass manufacturing, semiconductor production, and as a filler in many industrial applications. The electronics industry depends on ultra-pure silica.
