Application of silica sand

In silica sand processing, the unique physical and chemical characteristics of silica sand make silica sand play an important role in the aviation, aerospace, electronics, machinery and IT industry, especially in its internal molecular chain structure, crystal shape and lattice change law, which makes it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and so on. Its unique optical properties play an increasingly important role in many high-tech products.

Silica sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. It can be transported by air, by train and by water.

1.Glass: Flat glass, float glass, glass products (glass cans, glass bottles, glass tubes, etc.), optical glass, glass fibers, glass instruments, conductive glass, glass cloth and special anti-radiation glass and other major raw materials.

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 sulphuric acid tower, amorphous silica powder

6.Mechanical: 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. Coating: Fillers (to improve the acid resistance of coatings)

10. Aeronautics and Astronautics
