Quartz sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractories, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.

Application field and use

1. Glass

The main raw materials of flat glass, float glass, glass products (glass cans, bottles, glass tubes, etc.), optical glass, glass fibers, glass instruments, conductive glass, glass cloth and special anti-radiation glass, etc.

2. Ceramics and Refractories

Embryo and glaze for porcelain, raw materials for high silicon bricks for kilns, ordinary silicon bricks and silicon carbide, etc.
3. Metallurgy

Raw materials, additives and fluxes of silicon metal, ferrosilicon alloy and silicon-aluminium alloy, etc.
4. Architecture

Concrete, cementitious material, road building material, artificial marble, physical property testing material of cement (i.e. cement standard sand), etc.
5. Chemical Industry

Raw materials such as silica compounds and water glass, fillers for sulfuric acid tower, amorphous silica powder, etc.
6. Machinery

Major raw materials for foundry moulding sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, abrasive cloth, etc.)
7. Electronics

High purity metal silicon, optical fibers for communication, etc.
8. Rubber and plastics

Packing (to improve wear resistance)
9. Coatings

Fillers (to improve the weatherability of coatings)
10. Aerospace

Its intrinsic molecular chain structure, crystal shape and lattice change rule make it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance and its unique optical characteristics.

In fact, quartz is also a general term for crystals, because minerals that can be used as crystals are produced by quartz cutting and grinding. They all have the same characteristics of composition identification. The difference is that crystals can be used as gemstone-grade materials. After quartz is dyed, most of them can only be used as imitations of jades, such as Xiuyan Jade and Dushan Jade.
