Basic Properties and Applications of Quartz

Quartz is a hard, wear-resistant, chemically stable silicate mineral. Quartz mineral rock names are quartz, crystal, opal, flint, flint, agate, quartz sandstone, siliceous rock, quartzite, etc., the market application of the name of the quartz raw ore, vein quartz, lardite, quartz sand, silica sand, quartz powder, silica micropowder, sea sand, sand, sand, casting sand, glass sand, crystals, agate and so on.

Quartz as well as products for the chemical composition of the main components of SiO2, generally more pure, but often contains some of the main components of the study of relatively complex mechanical products into the material and particles can be inclusions,carrara quartz benchtops but also through the development of some other trace metal elements into a quartz technology structure to replace silicon. Pure quartz as a crystal has colorless transparent, but often contains some problem inclusions and trace nutrients and shows a different color, generally milky white, colorless, gray; glass surface luster, fracture grease luster. Specific gravity 2.22-2.65; Mohs hardness 7.0; PH value 6.0; melting point 1750 ℃; with piezoelectricity. Quartz powder is non-toxic, tasteless, non-polluting, good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, more stable chemical reaction properties, hardness. Quartz distribution is widely used in automotive glass, casting, ceramics and refractory design materials, metallurgy, construction, chemicals, plastics, rubber, abrasives, electronics, coatings, aerospace university aviation, jewelry and other industries.

Glass Industry: Quartz is the main raw material for manufacturing glass.calacatta gold quartz supplier Quartz glass is widely used because of its small coefficient of thermal expansion, good thermal shock stability, electrical properties and chemical resistance.

Ceramic industry: quartz has an important influence on ceramic blanks in the heating at room temperature. Before firing, quartz in the billet in the plasticity of the mud to play a moderating role, and can reduce shrinkage in drying, shorten the drying time and prevent deformation of the billet; in the firing, due to the expansion of the quartz heating to offset the billet properly burned Yu contraction; and when a large number of vitreous, the quartz has become a ceramic skeleton, which prevents billet bending and deformation defects occur in the firing. In addition, quartz can also increase the billet binding capacity, mechanical strength and transparency. Quartz used in ceramic glaze can increase the mechanical strength of the glaze, improve the hardness of the glaze, so that the porcelain crystal wear-resistant, and chemical stability is also good, not affected by acid erosion, but also can make the glaze transparent and bright.

Building materials industry: Ordinary quartz sand powder and refined quartz sand powder can be used to manufacture artificial quartz plate for kitchen and other countertops, can also be used for ceramic tile adhesive, dry mortar, cement standard sand, soccer field paving sand, etc., of which, artificial quartz stone has become a new type of countertop material in the world. The application of quartz powder in cement can improve the compression, crack resistance, impermeability, corrosion resistance, impact resistance and abrasion resistance of concrete, which can prolong the service life of concrete, reduce the fly ash of sprayed concrete and castables, and increase the thickness of the single-layer sprayed layer.

Foundry and Grinding:The market share of quartz sand products used in the foundry industry is about 40%. Foundry sand is used to prepare molding sand and core sand in production. Casting quartz sand can be divided into resin sand casting, water glass sand casting and disappearing mold casting. In addition, quartz sand is widely used as an abrasive material (sandblasting, hard sandpaper, sandpaper, emery cloth, etc.). .

Rubber: quartz powder is non-toxic, odorless, non-polluting, good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, chemical and technical properties are more stable, hardness and other excellent properties, widely researched and applied to improve the silicone rubber such as silicone rubber gloves, seals, shoe materials. Powdered quartz material as a filler can be used in the rubber industry products, such as in the battery shells, adding powdered quartz can be used instead of clay and lightweight nano-calcium carbonate and other fillers, the resulting battery shells without bubbles and cracking phenomenon, the shells are more even surface smooth appearance, high yield.

Paint: Quartz powder instead of precipitated barium sulfate and talc as a variety of dark-colored paint filler, not only can play a role in filling, but also improve the fineness of the paint, film hardness and water resistance, as well as rust and corrosion resistance, and at the same time reduce the cost of raw materials, the economic benefits are better.

Water Glass:Quartz sand and soda ash (or soda ash) in the smelting furnace co-melting, cooling and crushing can be made into water glass. Water glass is widely used in the chemical system for the manufacture of silica gel, silica, zeolite molecular sieve, sodium metasilicate, silica sol, sodium potassium silicate and other silicate products. In the light industry, it is an indispensable raw material in detergents such as laundry detergent and soap, as well as a water softener and settlement aid. It is used in dyeing, bleaching and sizing in textile industry; widely used in casting and metal anticorrosive in machinery industry; used in construction industry to make quick-drying cement, acid-resistant cement and waterproof oil, soil curing agent, refractory materials and so on. Silicon fertilizer can be manufactured in agriculture.

Electronic industry: defect-free crystal single crystal with piezoelectric properties, can be used to manufacture resonators, filters, and is widely used in automatic weapons, electronic microscopes, chronometers, electronic computers, artificial Earth satellites and other scientific and technological navigation, telecontrol, telemetry, electronic telecommunication equipment and other aspects.
