High-purity silica quartz sand price 180 mesh SiO2 98.0-99.20% low price

The unique physical and chemical properties of quartz sand play a very important role in today's rapid development of aviation, aerospace, electronics, machinery and IT industries, especially the internal structure, shape change and lattice of molecular chains, which have high temperature resistance and thermal expansion coefficient Low and high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties play an increasingly important role in many high-tech products.

Quartz sand is an important industrial mineral raw material, non-hazardous chemicals, widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. Automobile, train transportation, waterway transportation. Industrial production is generally packaged in 50KG or 25KG, and the export ton packaging specification: 0.5-1.0mm 0.6-1.2mm. 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm millimeter unit) ordinary quartz sand.

1. Glass: flat glass, float glass, glass products (glass bottles, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass equipment, conductive glass, glass cloth and special radiation-proof glass and other raw materials.

2. Ceramics and refractory materials: Common raw materials such as blanks and enamel, high-silicon bricks for kilns, and silicon carbide.

3. Metallurgical metal silicon, ferrosilicon alloy and silicon aluminum alloy and other raw materials or additives, flux

4. Construction: Concrete, cementitious materials, building materials, artificial marble, test material cement physical properties (cement standard sand).

5. Chemical industry: raw materials such as silicon compounds and water glass, fillers for sulfuric acid towers, amorphous silica powder

Six: Main raw materials, sand for mechanical casting, abrasive materials (sand, hard sandpaper, sandpaper, emery cloth, etc.)
