Can be made of glass: SiO2 + Na2CO3 = Na2SiO3 + CO2
SiO2 + CaCO3 = CaSiO3 + CO2

Quartz sand has a unique physical and chemical characteristics, making it in the aviation, aerospace, electronics, machinery and today's rapid development of the IT industry occupies a pivotal position, in particular its internal molecular chain structure, crystal shape and lattice changes It has an increasingly important role in many high-tech products because of its high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonant effect and its unique optical properties.
Quartz sand is an important industrial mineral raw materials, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastics, rubber, abrasive and other industries. Can be steamed, train transport, water transport. Industrial production is generally 50KG or 25KG packaging and export tons of bags. Common specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (Mm in millimeters)

Second, ceramics and refractories: porcelain embryo and glaze, kiln with high silica bricks, ordinary silicon brick and silicon carbide and other raw materials.
Third, metallurgy: silicon metal, ferrosilicon and silicon aluminum alloy and other raw materials or additives, flux
Fourth, the building: concrete, cementing materials, road materials, artificial marble, cement physical properties test materials (ie, cement standard sand), etc.
5, chemical: silicon compounds and water glass and other raw materials, sulfuric acid tower filler, amorphous silica powder
Six, machinery: casting sand main raw materials, grinding materials (sandblasting, hard grinding paper, sandpaper, emery cloth, etc.)
Seven, electronic: high purity silicon metal, optical fiber and so on
Eight, rubber, plastic: filler (can improve wear resistance)
Nine, paint: filler (can improve the acidity of paint)
