Quartz sand is a hard, wear-resistant, stable chemical properties of silicate minerals, the main mineral component of up to 99% of SiO2, quartz sand color with red or colorless translucent milky, Mohs hardness 7, sexual brittle cleavage, conchoidal fracture, oil sheen, the relative density of 2.65, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, the melting point of 1750 ° C. The color was milky white, yellow, brown and gray, quartz higher fire resistance. Price of quartz sand, sand-blasting the performance of quartz sand: chemical formula of quartz sand Si02, often contain a small amount of impurities such as A1203, IMO, CaO, Mg0, etc.. It has a variety of types. Daily-use ceramic raw materials used in vein quartz, natural quartz sand, quartzite, sandstone, silica, opal, diatomaceous earth, rice shell ash-rich Si02. Quartz appearance Changcheng white, milky white, gray translucent state, Mohs hardness of 7, the off mask glass gloss or fat gloss, the proportion of different polymorphs, movements between 2.22-2.65. Quartz non-plastic materials, with the clay at a high temperature generated mullite crystals gives porcelain of high mechanical strength and chemical stability, and can increase the translucency of the blank, good raw material for the preparation of white glaze. Quartz is one of the Earth's surface is the most widely distributed minerals, it is also a wide range of uses. Far in the Stone Age, people use it to produce simple production tools, stone axes and arrows, to hunt for food and fighting the enemy. Quartz clock, electronic devices, piezoelectric quartz plate is used as a standard frequency; made of molten glass can be used for the production of optical instruments, glasses, glass tube and other products; can do precision instrument bearings, abrasive materials, glass, ceramics, etc. industrial raw materials. The quartz body contains tiny bubbles or liquid-filled fissures, by interfering with the light producing rainbow, made of fine jewelry. Price of quartz sand, sand-blasting quartz sand purposes: quartz sand addition to the main ingredient silica, further contains iron oxide, alumina, lead, boron, magnesium, sodium, and other trace elements. The quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramic and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries. Trucking, rail transport, water transport. Quartz sand in glass industry for the production of: flat glass, float glass, glass products (glass jars, glass bottles, glass tube, etc.), optical glass, glass fibers, glass instrument, conductive glass, glass arming ray specialty glass and other major raw materials. Mainly used in ceramics and refractories: porcelain billet and glaze, kiln raw material with a high silica brick, silica brick, and silicon carbide. Mainly used in metallurgy: silicon metal, ferrosilicon alloy and silicon aluminum alloy raw materials or additives, flux. Is used in the construction: concrete, cementitious material, road building materials, artificial marble, cement physical performance test materials (cement standard sand). : Silicon compound and water glass and other raw materials, a filler of the column used in the chemical industry, the amorphous silica dioxide. The main raw material for foundry sand in the machinery sector, abrasive material (sand blasting, the hard abrasive paper, sandpaper, emery cloth, etc.). Is used in the electronics industry: high-purity silicon metal, communication optical fiber such as rubber, plastic filler (can increase the wear resistance) paint filler (which can improve the weather resistance of the coating) the Lingshou Yijia Mining Co., Ltd. specializing in the production of quartz sand.
