Quartz sand is quartz grains made from crushed quartz stone. Quartz stone is a non-metallic mineral. It is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO₂. The color of quartz sand is milky white, colorless, and translucent, and the Mohs hardness is 7. It is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials, and other industries.

Main categories:
Quartz has high refractory performance. In industry, quartz sand is usually divided into ordinary quartz sand, high-purity quartz sand, fused silica sand, and silicon micro powder.
Quartz has high refractory properties. In industry, quartz sand is usually divided: into ordinary quartz sand, high-purity quartz sand, fused silica sand, and silicon micro powder.
1. Common quartz sand:
It is a water treatment filter material made from natural quartz ore after crushing, washing, drying, and secondary screening; the filter material has no impurities, no edges and corners, it has high density, high mechanical strength, and no pollution. Capacity lines have a long service life and are ideal for chemical water treatment.
Main applications:
metallurgy, ink silicon carbide, glass enamel sodium hydroxide, chemical industry, noise spray, and other industries.
2. Refined quartz sand:
(1) It is also known as pickled quartz sand
(2) SiO₂≥99-99.5%
(3) Fe₂O₃≤0.005%
(4) Using high-quality natural quartz sand and mortar.
3. High-purity quartz sand:
(1) SiO₂≥99.5—99.9%
(2) Fe₂O₃≤0.001%,
(3) Using high-quality natural quartz stone and mortar.
