Summary Quartz sand is a hard, wear-resisting, stable chemical property of silicate minerals, the main mineral composition is SiO2, quartz sand color is milky white, or colorless translucent, a multi edge type ball of white crystal, hardness, brittle cleavage, conchoidal fracture, oily luster, density is 2.65, bulk density (1-20 1.6), 20-200 head is 1.5, the chemical, thermal and mechanical properties has obvious differences to, insoluble in acid, slightly soluble in KOH solution, melting point 1750 DEG C. Quartz sand application Quartz sand is a unique physical and chemical properties, making it occupies a pivotal position in the aviation, aerospace, electronics, machinery, and today, with the rapid development of IT industry, especially in the inner molecular chain structure, crystal shape and lattice changes, so that it has high temperature resistance, thermal expansion coefficient is small, high insulation, corrosion resistance, piezo electric effect, resonance effect and the unique optical properties, is playing a more and more important role in many high-tech products. Fine quartz sand can be used as abrasive, such as grinding glass: Glass: flat glass, float glass, glass (glass jar, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and anti ray special glass as the main raw material. Second, ceramics and refractory materials: embryo material and porcelain glaze, kiln with high silica brick, ordinary brick and silicon carbide and other raw materials. Three, metallurgy: silicon metal, ferrosilicon alloy and silicon Aluminum Alloy and other raw materials or additives, flux Four, construction: concrete, cementitious materials, road materials, artificial marble, cement physical performance test materials (cement standard sand) Five, chemical: silicon compounds and water glass and other raw materials, sulfuric acid tower filler, amorphous silica powder Refractory quartz sand application Refractory quartz sand is the main component of quartz sand. According to various needs to add different additives. Scientific formula. Advantages of low price, good acid resistance, non stick slag. All required materials for metal smelting induction furnace lining. The main technical indicators: SiO2 = 97.5%Al2O30.7---0.3%Fe2O30.4---0.1%H2O = 0.5% Bulk density: 1.9----2.1g/cm fand Liner volume density: 1.75---1.8g/ cm fand Fire resistance: A[1500---1700 advisable] Fire resistance: H, C[1300---1450] advisable size: 5.1-----0.021mm Refractory quartz sand used in smelting non-ferrous metal, black power, frequency, frequency conversion, core induction furnace lining
Fused silica has high working and melting temperatures and it differs from traditional glasses in containing no other ingredients than silica in amorphous. The optical and thermal properties of fused quartz are superior to those of other types of glass due to its purity. It has better ultraviolet transmission than most other glasses, and so is used to make lenses and other optics for the ultraviolet spectrum. Small thermal expansion coefficient, good chemical stability, bubbles, stripes, homogeneity, birefringence makes it very proper material for optical fiber base product. Mainly Applied: special light source, optics, optoelectronics, military industry, metallurgy, semiconductors, optical communications and other fields.
It is a high-purity silicon tetrachloride synthetic optical quartz glass containing a large amount of hydroxyl (2000ppm). It has excellent UV properties of the lens, particularly in the short-wave UV region, which far better than all the other transmission properties of glass, at a transmittance of 90% 185�¼m, synthetic quartz glass has a strong absorption peak at 2730nm at no granular structure. Is an excellent optical materials within 185-2500m�¼ band range.
Fused quartz materials and vacuum production of quartz glass, several tens of ppm of metal-containing impurities. Small bubbles, particles and striped structure, almost no (OH), with higher performance through the infrared transmittance over 85%, and its applications in the wavelength range of 260-3500m optical material.
Quartz sand Product details Quartz sand is produced from quartz, a silica mineral.Quartz is the only mineral consisting exclusively of silicon and oxgyen with well bonded ions which make it extremely hard. After crushing, hand-sorting, washing, drying, grinding, screening, the quartz is processed into different specifications ranging from 4 mesh to 325 mesh. Feature High purity High bulk density Highhardness Resistance to acids alkalies Insolubility in water Specification: 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20mesh, 20-40mesh, 40-80mesh, 80-120mesh, 200mesh, 325mesh.
