Quartz is a hard, abrasive, chemically stable silicate mineral.
Quartz, inorganic minerals, the main component is silica, often containing a small amount of impurities such as Al2O3, CaO, MgO, etc., for the translucent or opaque crystals, generally milky white, hard texture. Quartz is a physical property and chemical properties are very stable mineral resources, the crystal is a triad of oxide minerals, that is, low temperature quartz (a-quartz), Quartz is the most widely distributed mineral mineral species. The generalized quartz also includes high temperature quartz (b-quartz). Stone block, also known as silica, is mainly the production of quartz sand (also known as silica sand) of raw materials, Quartz but also quartz refractory materials and ferrosilicon raw materials.
Quartz name, quartz stone, stone, opal, flint, agate, quartz sandstone, siliceous rock, quartzite, etc., the market name is quartz ore, vein quartz, lime stone, quartz sand, silica sand, Quartz powder, silicon powder, sea sand, river sand, foundry sand, glass sand, crystal, agate and so on.
Quartz crystal, quartz crystal, blue quartz, milk quartz, grass into the crystal, Venus stone, cat's eye stone, tiger eye stone, eagle eye stone; quartz hidden; quartz crystal Crystalline variants include chalcedony, agate, flint, jasper, opal, opal, pyrotechnic, opal, glass opal, opal, pearl opal, opal and so on.
Quartz Ingredients: quartz chemical composition is mainly SiO2, Quartz generally more pure, but often contain some of the relatively complex composition of the mechanical mixture and particle inclusions, Quartz there may be some trace elements into the quartz structure to replace silicon.
Quartz nature: pure quartz crystal colorless and transparent, Quartz but often contains some inclusions and trace elements and show different colors, usually milky white, colorless, gray; glass luster, broken oil luster. Specific gravity: 2.22 ~ 2.65; Mohs hardness: 7.0; PH value: 6.0; melting point 1750 ℃; with piezoelectricity. Quartz powder non-toxic, tasteless, non-polluting, good temperature resistance, acid and alkali corrosion, Quartz poor thermal conductivity, high insulation, low expansion, chemical stability, hardness.
Quartz used: quartz widely used in glass, casting, ceramics and refractories, metallurgy, construction, chemicals, plastics, rubber, abrasive, electronics, coatings, aerospace, jewelry and other industries.
Quartz is the main raw material for the manufacture of glass, quartz glass due to a small coefficient of thermal expansion, thermal shock stability, good electrical properties, Quartz good chemical resistance and other characteristics, has been widely used.
Quartz has an important effect on the heating of the ceramic body at room temperature. Before sintering, the quartz in the blank material on the plasticity of the role of the transfer agent, and can reduce the shrinkage in the dry, shorten the drying time and prevent the deformation of the body; in the firing, Quartz due to the heating of quartz expansion of the blank And when the vitreous mass appears, the quartz has become the skeleton of the ceramic, can prevent the body in the firing when the bending deformation and other defects. In addition, quartz can also increase the body binding capacity, mechanical strength and transparency.
Quartz for ceramic glaze can increase the mechanical strength of glaze, Quartz improve the glaze hardness, so that porcelain wear, and chemical stability Ye Hao, not affected by the erosion of acid, but also make the glaze transparent light.
