What is quartz stone? What are the uses of quartz stone?

Quartz is a physical and chemical properties are very stable mineral resources, and quartz is a more than 90% of the quartz crystal with resin and other trace elements synthetic a new type of stone, its main material is quartz , So called quartz stone. Quartz stone mostly milky white or crystal translucent, hard texture, Mohs hardness of 7.0; melting point of 1750 ℃. Quartz stone is mostly silica, its content in more than 98.5%. Mainland China is rich in quartz mine resources: mainly in: Jiangsu, Henan, Shaanxi, Hubei, Hunan, Hebei, Yunnan, Guangxi, Jiangxi, Anhui, Qinghai and Liaoning, Heilongjiang and other places. Among them, the quality of the quartz resources of Jiangsu Donghai is the most abundant. The quartz reserves in the Hanzhong basin, which is called "the small northwest of the northwest", are the most abundant. Most of the other areas are quartz-type mines or small-scale mines (such as Anhui Fengyang, Henan Luoyang, etc.).

Quartz stone is widely used, the most used is the production of construction or construction of the use of sand and gravel material, through the crushing equipment and sand equipment can be made of quartz stone specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (Mm in millimeters) of the gravel material for construction and construction. Quartz stone texture is hard, made of gravel quality can be used for various industries gravel demand. Quartz stone with its special color and appearance, making the use of quartz sand is more extensive, special quartz stone with stars, purple, ink, milky white and translucent, etc., no pollution, no taste, no burning, high whiteness, no impurities , Low iron content, the finished sand can be used as ornaments and ornaments for high-level hotels, pots of art, beach, bath, flowers and so on. Quartz quartz can also be used to smelt jewelery; pure quartzite with optical rotation and through the ultraviolet performance, can be used for enamel and silicon Ceramic materials; also widely used in the radio industry, ultrasonic technology and modern defense and cutting-edge technology; can manufacture a variety of optical instruments and medical use of quartz lamps, but also the manufacture of corundum (silicon carbide) basic raw materials. Fine quartz sand can be used for filtering. Quartz sandstone, mainly used for glass products, foundry industry, metallurgical industry, ceramic uranium, refractories, cement industry, chemical industry
