What industrial fields can quartz sand be used in?
September.19,2023
Quartz sand is an important industrial mineral raw material and is widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.
1. Glass
Flat glass, float glass, glass products (glass jars, bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass
Main raw materials for quartz crucible glass, glass cloth and radiation-proof special glass
2. Ceramics and refractory materials
Porcelain blanks and glazes, raw materials for kilns such as high silica bricks, ordinary silica bricks and silicon carbide
3. Metallurgy
Raw materials or additives and solvents for silicon metal, ferrosilicon alloy, silicon-aluminum alloy, etc.
4. Architecture
Concrete, cementitious materials, road construction materials, artificial marble, cement physical performance testing materials (i.e. cement standard sand), etc.
5. Chemical industry
Raw materials such as silicon compounds and water glass, filling materials for sulfuric acid towers, amorphous silica powder, etc.
6. Machinery
The main raw materials of casting sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.)
7. Electronics
High-purity metallic silicon, optical fiber for communication, crystal oscillator, piezoelectric crystal, etc.
8. Rubber, plastic
Fillers (can improve wear resistance)
9. Paint
Fillers (can improve the weather resistance of coatings)
10. Aviation and aerospace
Its inherent molecular chain structure, crystal shape and lattice change law make it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance and its unique optical properties.
