Examples
- Silicon oxide is one of the primary components of ordinary sand and of glass.
- The silicon oxide content in the earth's crust is extremely high due to its several forms like quartz.
- Quartz, a type of silicon oxide, accounts for at least 12% of the earth's crust by volume.
- Silicon oxide, in the form of lechatelierite, is also found in some meteorite impact zones around the world.
- Due to its high thermal stability and low coefficient of thermal expansion, silicon oxide is used as a refractory in high temperature applications.
