What is the difference between quartz and crystal?
Quartz sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.Application areas / applicationsGlassFlat glass, float glass, glass products (glass cans, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and anti radiation special glass and other main raw materialsCeramics and refractories..crystalCrystal is a colorless transparent quartz crystal mineral. The main chemical it is silicon dioxide, with the ordinary sand is a kind of material with out of the womb ".
Quartz sand is a hard, wear-resistant, stable chemical properties of silicate minerals, its main mineral composition is SiO2, quartz sand color is milky white or colorless and translucent, 7 hardness, brittle cleavage, conchatus fracture, oil sheen, relative density is 2.65, the chemical, thermal and mechanical properties have obvious the anisotropy, insoluble in acid, slightly soluble in KOH solution, the melting point of 1750 DEG C.Quartz can be divided into ordinary quartz sand according to its quality, refined quartz sand and specially refined quartz sand.
Quartz and crystal are mainly composed of Si02quartzQuartz is a kind of physical and chemical properties of mineral resources are very stable, the crystal belongs to the three party system of oxide minerals, namely low quartz (a- quartz, quartz) is the most widely distributed group minerals in a mineral species. The broad quartz also includes high temperature quartz (b- quartz). Also known as quartz block silica, mainly the production of quartz sand (also called silica) raw material is quartz refractory material and firing ferrosilicon raw materials.Quartz chemical formula is Si02, often contain a small amount of impurities, such as A1203, IMO, CaO, Mg0 and so on. It comes in many different types. The raw materials used for daily use are quartz, quartz sand, quartzite, sandstone, silica, opal, diatomite, etc., and the rice hull ash is also rich in Si02. The appearance of quartz is usually white, milky, gray and semi transparent, Mohs hardness is 7, broken glass luster or fat luster, the proportion varies because of crystal type, change between 2.22-2.65.The quartz is non plastic materials, the porcelain with higher clay formation at high temperature and the mullite crystal mechanical strength and chemical stability, and can increase the translucent body, is a good material for the preparation of white glaze.
