Quartz silica sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white or colorless and translucent, with a hardness of 7, which is brittle and has no cleavage. Shaped fracture, grease luster, density 2.65, bulk density (1-20 mesh is 1.6-1.8), 20-200 mesh is 1.5, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 °C.
Due to the unique physical and chemical properties of quartz silica sand, it has high-temperature resistance, low thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect, and unique optical properties. It is mainly used in glass, ceramics, and refractory materials, metallurgy, construction, chemicals, mechanical casting, electronic aerospace, rubber and plastics, coatings, water purification, etc.
