Quartz sandis a hard, wear-resistant and chemically stablesilicate mineral, itsmain mineralcomponent isSiO2 . The colors of quartz sand are diverse, often milky white, colorless and gray. Its hardness is7, it is brittle and has nocleavage,conchoidal fracture. Greasy luster, with a density of2.65 g/cm³. Its chemical, thermal and mechanical properties have obviousanisotropy. It is insoluble in acids and slightly soluble inKOH solution, with a melting point of1750℃. It hasPiezoelectricity.
Quartz is one of the most widely distributed minerals on the Earth's surface. There are various types of quartz. Those used in daily ceramic raw materials includeVein quartz,Quartz sand,Quartzite, sandstone,Silica,Opal,Diatomite, etc. It is a substance that is "from the same origin" as ordinary sand and crystal. When silicon dioxide crystallizes perfectly, it becomes crystal,Silicon dioxideAfter gelatinization and dehydration, it becomesagate. When the silica-containingcolloidsolidifies, it becomes opal. When the silica crystal grains are less than a few micrometers, they formchalcedony,
Its uses are also quite extensive. As far back as the Stone Age, people used it to makestone axes,stone arrowsand other simple production tools to hunt for food and fight against enemies [2] .Quartz clocks, in electronic devices, usepiezoelectric quartzThe slices are used as standard frequencies.FusedThe glass made after melting can be used to make optical instruments, glasses, glass tubes and other products. It can also be used as industrial raw materials for bearings of precision instruments, grinding materials, glass ceramicsetc.
Shaoyang Zhongcai Manufacturing Co., Ltd.is located on the banks of the Zijiang River, in the historical city of Shaoyang, with unique geographical conditions and convenient water and land transportation. It independently produces and sells natural quartz powder, which is mainly used in foundry, filter materials and dust removal etc. It has abundant ore sources, which are naturally formed by impact. The original sand has a high grade and good quality, with the advantages of full particles, compression resistance, wear resistance, high temperature resistance and good adsorption. Through careful screening and strict testing, the silica sand series products sold are well - received by users and are reliable auxiliary materials for the mechanical casting industry and acid - and alkali - resistant projects.
