SiO2 is silicon dioxide (just as CO2 is carbon dioxide) and is more commonly known as silica, which in the form of a network solid is the primary constituent of sand and glass. http://www.the-piedpiper.co.uk/th13(a).htm

In the semiconductor industry, SiO2 is important as the insulating oxide barrier that is grown over a silicon-based device.
