The main classification of quartz silica sand has a higher fire resistance, quartz sand industry will often be divided into: ordinary quartz sand, fine quartz sand, high purity quartz sand, fused silica sand and microsilica. Ordinary quartz sand ordinary quartz sand, which SiO2≥90-99% Fe2O3≤0.06-0.02%, refractoriness 1750 ℃, the appearance of some large particles, the surface of yellow cysts. Size range 5-220, user requirements particle production. Main purpose: metallurgy, Mexico silicon carbide, glass and glass products, ceramic, steel, water filtration, sodium silicate, chemicals, spraying noisy industries. Refining quartz sand, also known as pickling quartz sand, SiO2≥99-99.5% Fe2O3≤0.005%, using high-quality natural quartz sand, carefully selected, fine fine quartz sand processing. Size range 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user requirements. Uses: manufacture of glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, quartz sand casting molding, etc., in the building with its strong acid etching medium capacity, extracting acid and acid of concrete mortar . Refining quartz sand SiO2≥99-99.5% Fe2O3≤0.02-0.015%, selection of high quality ore processing complex. With 5-480 mesh size range, according to user requirements, the appearance of white or crystalline. Main purpose: Senior glass and glass products, refractories, melting stone, quartz sand casting specifications, grinding wheel and other materials. (Mm for millimeters) of quartz glass can be manufactured quartz sand, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials 0.5-1 quartz sand casting, quartz stone in the construction of its use of strong acid medium etching capability, used for extracting acid and acid of concrete mortar. Silica as a core raw material silicon feedstock plays an irreplaceable role in the production and supply of basic raw material of silicon. It has the unique physical, chemical optical properties, making it plays an increasingly important role in many high-tech products, such as, IT industry's core technology products - computer chips, fiber optics, electronics industry resonator , the new electric light, high insulation sealing materials, aerospace equipment quartz sand quote, military technology products, special optical glass, chemical analysis instruments, etc., are inseparable from these basic materials. Beautiful crystalline quartz and shape can be used for glasses and precious crafts using piezoelectric quartz crystal can be made without the wire industry frequency stabilizer, quartz filters. Can produce various lenses, reflectors, spectral tube, the optical waveguide and optical instruments prisms, polarizers and the like. Has been widely used to make artificial hydrothermal quartz crystal temperature difference method for the manufacture of the piezoelectric element. In the chemical industry, quartz can be used for acid temperature instruments and utensils; in the electrical industry, often using quartz as excellent insulating materials; quartz is an excellent glass, enamel and refractory brick manufacturing industry raw materials; melting quartz outstanding performance also it is widely used in metallurgy, food, pharmaceutical and paper industries. Export of quartz (sand) mostly used in metallurgy and refractory industries. Quartz tube, gray quartz, black quartz, blue quartz tubes, etc., but also the production of filter UV quartz tube, transparent quartz tube, quartz rods, and other quartz products.
