Quartz sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.
1. Glass
The main raw materials of flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and special radiation-proof glass.
2. Ceramics and refractories
Porcelain blanks and glazes, raw materials for high silica bricks, ordinary silica bricks, silicon carbide, etc. for kilns.
3. Metallurgy
Raw materials or additives and fluxes for silicon metal, ferrosilicon alloy, silicon aluminum alloy, etc.
4. Construction
Concrete, cementitious materials, road construction materials, artificial marble, cement physical performance test materials (ie cement standard sand), etc.
5. Chemical industry
Raw materials for silicon compounds and water glass, fillers for sulfuric acid towers, amorphous silica powder, etc.
6. Machinery
The main raw material of foundry sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.).
7. Electronics
High-purity metal silicon, optical fiber for communication, crystal oscillator, piezoelectric crystal, etc.
8. Rubber and plastic
Filler (to improve wear resistance)
9. Paint
Fillers (to improve weather resistance of coatings)
10. Aerospace
Its internal molecular chain structure, crystal shape and lattice change law. It has excellent high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance and its unique optical characteristics.
11. Jewelry
Quartz is actually the mineral name of crystal, which has the same chemical composition. The difference is that gem-grade crystal can be used as a gem material and can be processed into various accessories. After the polycrystalline quartzite is dyed, most of it can only be used as imitations of jade, such as: jadeite, Xiuyan jade, Dushan jade, etc. Single crystal quartz can also be exploded first and then dyed to imitate gemstones such as tourmaline.
