Quartz Sand

Quartz sand is a quartz particle formed by crushing and processing quartz stone. Quartz is a non-metallic mineral, which is a hard, wear-resistant, and chemically stable silicate mineral. The color of quartz sand is milky white or colorless and semi transparent, with a Mohs hardness of 7.
Quartz sand is an important industrial mineral raw material, not a chemical hazardous material, widely used in industries such as glass, casting, ceramics and fireproof materials, smelting of ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials, etc.
