Quartz sand

Quartz sand is a stable mineral at room temperature and is insoluble in water, sulfuric acid, hydrochloric acid, and nitric acid.Hardness 7, specific gravity about 2.65, melting point 1713℃.The gloss is glassy and sometimes fatty.Those with pure texture are colorless; those with impurities are red, yellow, blue, black, brown, purple, and green; transparent to opaque, and brittle.The fracture is shell-like or jagged.The crystal is in the shape of a hexagonal column with horizontal stripes on the column.

The unique physical and chemical properties of quartz sand make it play a pivotal role in aviation, aerospace, electronics, machinery and today’s rapidly developing IT industry, especially its internal molecular chain structure, crystal shape and crystal lattice change law , It has high temperature resistance, low thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical characteristics, which play an increasingly important role in many high-tech products.

Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.It can be transported by motor, train, or water.Industrial production is generally 50KG or 25KG packaging and export ton bag packaging.Common specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm is in millimeters)

1. Glass: The main raw materials of 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: raw materials for porcelain blanks and glazes, high-silicon bricks for kilns, ordinary silicon bricks and silicon carbide.

3. Metallurgy: raw materials or additives and fluxes of silicon metal, ferrosilicon alloy and silicon aluminum alloy

4. Construction: concrete, cementitious materials, road construction materials, artificial marble, cement physical performance inspection materials (ie cement standard sand), etc.

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

6. Machinery: The main raw material for foundry sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.)

7. Electronics: high-purity metallic silicon, optical fiber for communication, etc.

8. Rubber, plastic: filler (can improve wear resistance)

9. Coating: Filler (can improve the acid resistance of the coating)

10. Aviation and aerospace.
