Jul 10 2020 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.
