  • Quartz stone has high content of SiO2 and less impurities. Quartz sand characteristics: Quartz hardness is 7, relative density of 2.65, colors are milky white, light yellow, brown and gray. Quartz has a higher fire resistant; melting point is 1730 ℃, mainly used to process quartz sand and quartz powder.

    Quartz powder is made by crushing and screening of quartz ore. Quartz sand (powder) is mainly used in glass, ceramics, enamel, hot bottle, sodium citrate, casting, building materials, grinding, fire resistance, water filtration, military, communication and other industries.

    Quartz sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white or colorless and translucent. Its hardness is 7. It is brittle and has no cleavage, shell-like fracture, grease luster, relative density of 2.65. Its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750℃. The color is milky white, light yellow, brown and gray, and quartz has high fire resistance.

    The unique physical and chemical properties of quartz sand make it play an important role in aviation, aerospace, electronics, machinery and the rapidly developing IT industry. Especially its intrinsic molecular chain structure, crystal shape and lattice change pattern make it with high temperature resistance, small coefficient of thermal expansion, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties, playing an increasingly important role in many high-tech products.

    Uses: manufacturing glass, fire resistance materials, smelting ferrosilicon, metallurgical flux, ceramics, grinding materials, casting. In the construction industry, people use quartz's strong acid-resistant medium etching ability to produce acid-resistant concrete and acid-resistant mortar. As the core raw material of silicon raw materials, quartz sand plays an important and irreplaceable role in the production and supply of silicon raw materials.
