The purpose and effect of quartz sand

Quartz sand is an important industrial mineral raw materials, widely used in glass, foundry, ceramics and refractories, metallurgy, construction, chemicals, plastics, rubber, abrasive and other industries.
Applications \ Application:
Glass:
Flat glass, float glass, glass (glass jars, bottles, glass, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth, and radiation-shielding the main raw material of special glass.
Ceramics and refractories:
Blank porcelain and glazes, kilns with a high silica, silica and silicon carbide and other common materials.
Metallurgy:
Silicon metal, ferrosilicon and silicon aluminum and other raw materials or additives, flux.
Construction:
Concrete, cementitious material, road building materials, artificial marble, cement physical performance test material (ie cement standard sand) and so on.
Chemicals:
Silicon compound and water glass and other raw materials, sulfuric acid tower fillers, amorphous silica powder.
Machinery:
The main raw material foundry sand, abrasive material (sand, hard abrasive paper, sandpaper, emery cloth, etc.).
Electronics:
High purity silicon metal, communication with optical fiber.
Rubber & Plastics:
Filler (can improve the wear resistance).
Coatings:
Fillers (which can improve the coating weatherability).
Quartz crystal is actually referred to, as may be used as a mineral crystal, are made of quartz Cutting outputs; identification of other components are the same characteristics, except that the crystal is used as a material gem; the silica after staining, Most only as a kind of imitation jade.
