Silica Sand Introduction Quartz sand is quartz stone processed by the crushing of quartz particles. Quartz stone is a nonmetallic mineral, a hard, wearable, chemical properties and stability of silicate minerals, the main mineral composition is SiO2.
Silica sand products are marketed in a wide range of grades, including extremely fine grades known as flours. The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity.
