Physical properties of quartz sand. Quartz sand is quartz particles made by crushing and processing quartz stone. Quartz is a non-metallic mineral, a hard, wear-resistant and chemically stable silicate mineral. Its main mineral component is SiO2, with a melting point of 1713°C. The luster is glass-like, and the fracture is shell-like or staggered.
