Quartz powder is used for a variety of purposes

Refined quartz sand and quartz powder are processed from high-purity quartz ore, and the products are of high grade (SiO2 = 99.82). %, Fe2O3 = 0.37, Al2O3 = 0.072, CaO = 0.14), white color, strong hardness (more than 7 degrees Mohs).
 
The fine quartz sand is washed, crushed, and sieved into various specifications of quartz sand. The produced quartz powder has unique slippery properties and the fineness is above 300 mesh.
 
The main purpose of fine quartz sand: to provide raw materials and auxiliary materials for ceramics, enamel, precision modeling, chemicals, coatings, building materials, metallurgy, advanced glass, metal rust removal, polishing, water treatment and other users.
 
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. Shape, hardness 7, brittle without cleavage, shell-shaped fracture, grease luster, the density of 2.65, bulk density (20-200 mesh is 1.5), its chemical, thermal and mechanical properties have obvious anisotropy, and it does not dissolve acid, Miniature KOH solution, melting point 1650℃.
 
The use of quartz powder
 
Quartz powder is not divided into grades, only specifications. Because of its high whiteness, no impurities and low iron content, it has a wide range of applications.
 
Glass: The main raw materials of flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass equipment, conductive glass, glass cloth and special radiation-proof glass.
 
Ceramics and refractory materials: raw materials for porcelain blanks and glazes, high-silicon bricks for kilns, ordinary silicon bricks and silicon carbide.
 
Construction: concrete, cementitious materials, road construction materials, artificial marble, cement physical performance inspection materials (ie cement standard sand), etc.
 
Chemical industry: raw materials for silicon compounds and water glass, fillers for sulfuric acid towers, and amorphous silica powder.
 
Machinery: The main raw material for foundry sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.).
 
Electronics: high-purity metal silicon, optical fiber for communication, etc.
 
Rubber, plastic: filler (can improve wear resistance).
