Silica 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: silica sand is main raw materials for 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 refractory materials: used as blanks and glazes for porcelain, raw materials for high-silica bricks for kilns, ordinary silica bricks, and silicon carbide.

3. Metallurgy: raw materials or additives, fluxes for silicon metal, ferrosilicon alloy and 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, filling materials for sulfuric acid towers, amorphous Silica powder

6. Machinery: quartz sand is 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, etc.

Eight, rubber, plastic: filler (can improve wear resistance)

9. Coatings: Fillers (can improve the acid resistance of coatings)

10. Aeronautics and aerospace: Its internal molecular chain structure, crystal shape and lattice change law, and has high temperature resistance, small thermal expansion coefficient, corrosion resistance, high insulation, piezoelectric effect, resonance effect and its unique optical characteristics.
