High Quality SILICA QUARTZ LUMPS
Quartz sand a unique physical and chemical properties, make its in aviation, aerospace, electrical machinery and the rapid development of today's foot or position in the IT industry, especially its internal molecular chain structure, crystal shape alloy change rule, has the high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect and resonance effect and its unique optical properties, is playing a more and more important role in many high-tech products.
Silica, or more correctly silicon dioxide SiO2, is one of the most abundant compounds on the surface of the Earth, being most obvious as quartz and common sand. Silica has a multitude of uses depending on the degree of purity. Grades up to 99.5% SiO2 are used in the manufacture of glass, optical fibres and ceramics.
Main USES:
Quartz sand a unique physical and chemical properties, make its in aviation, aerospace, electrical machinery and the rapid development of today's foot or position in the IT industry, especially its internal molecular chain structure, crystal shape alloy change rule, has the high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect and resonance effect and its unique optical properties, is playing a more and more important role in many high-tech products.
Use of quartz sand:
1: glass: flat glass, float glass, glass products (glass bottles, glass cans, glass tubes, etc.), optical glass, glass fiber glass instruments, conductive glass, glass cloth and anti-ray special glass and other raw materials
2. Ceramics and refractories: raw materials of high silica brick, common silica brick and silicon carbide are required for glaze and blank of porcelain
3. Metallurgy: raw materials or additives of silicon metal, ferrosilicon alloy and si-al alloy, flux
4. Four: building concrete, cementitious materials, road building materials, artificial marble, cement physical performance test materials (cement standard sand)
5. Chemical industry: raw materials of silicon compounds and sodium silicate, fillers for sulfuric acid towers, amorphous silica powder (cement standard sand), etc
6. Machinery: main raw materials of foundry sand, grinding materials (sandblasting, hard abrasive paper, sandpaper, gauze), etc
7. Electronics: high purity silicon, optical fiber for communication, etc
8. Rubber and plastics: fillers (to improve wear resistance); coatings: fillers (to improve acid resistance); aerospace
