[0002] Quartz sand is a kind of hard, wear-resistant and chemically stable silicate mineral. Its main mineral component is quartz, generally milky white or colorless and translucent, with a hardness of 7, brittle and without dissociation, conchoidal fracture, greasy luster, a density of 2.65. Its chemical, thermal and mechanical properties have obvious anisotropy. It is insoluble in acid, slightly soluble in KOH solution, and has a melting point of 1750 °C. The mineral types of quartz sand usually can be divided into quartz sandstone, quartzite, vein quartz, quartz sand, quartz sand ore, etc.

[0003] As the core raw material of silicon raw materials, silicon dioxide plays an irreplaceable and important basic role in the production and supply of silicon raw materials.
