Quartz is the most abundant and most common mineral on the Earth. It is found in almost every geological environment and also it is at least a component of almost every rock type. It has a hexagonal crystal structure and is made of trigonal crystallized silica. It is most varied in terms of varieties, colors and forms. Physical Properties of Quartz Quartz 1 Silica SiO2 99.9% (+/- 0.2%) Alumina Al2O3 0 Ferric Oxide Fe2O3 0.07% (+/-.01%) Titanium Oxide TiO2 0 Sodium Oxide Na2O 0 Pottasium Oxide K2O 0 Loss on Ignition LOI 0.16% Applications of Quartz User of Quartz Powder are spread over a very wide range of industry where functional roles of it are also varied, like quartz powder is used as a filler in porcelain, ceramics, sanitary ware and Engineered stone industry while quartz grains are used a lining refractories in induction furnaces, as a flux in smelting operations.
Quartz, widely distributed mineral of many varieties that consists primarily of silica, or silicon dioxide (SiO2). Large amounts of quartz sand (also known as silica sand) are used in the manufacture of glass and ceramics and for foundry molds in metal casting. Crushed quartz is used as an abrasive in sandpaper, silica sand is employed in sandblasting, and sandstone is still used whole to make whetstones, millstones, and grindstones. Silica glass (also called fused quartz) is used in optics to transmit ultraviolet light. Tubing and various vessels of fused quartz have important laboratory applications, and quartz fibers are employed in extremely sensitive weighing devices. Because of its piezoelectric property, a quartz plate can be used as a pressure gauge, as in depth-sounding apparatus. Quartz is very resistant to both chemicals and heat. It is therefore often used as foundry sand. With a melting temperature higher than most metals, it can be used for the molds and cores of common foundry work. Refractory bricks are often made of quartz sand because of its high heat resistance. Quartz sand has a high resistance to being crushed. In the petroleum industry, sand slurries are forced down oil and gas wells under very high pressures in a process known as hydraulic fracturing. The open fractures facilitate the flow of natural gas into the well bore. Quartz crystals are used to make oscillators for watches, clocks, radios, televisions, electronic games, computers, cell phones, electronic meters, and GPS equipment. Quartz makes an excellent gemstone. Based on the application and customer requirement, quartz can be supplied in specified size. The three main variants are quartz powder, quartz lumps and quartz grits.

Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO2). It is the most abundant mineral found at Earth's surface, and its unique properties make it one of the most useful natural substances. Quartz is one of the most useful natural materials. Its usefulness can be linked to its physical and chemical properties. It has a hardness of seven on the Mohs Scale which makes it very durable. It is chemically inert in contact with most substances. It has electrical properties and heat resistance that make it valuable in electronic products. Its luster, color, and diaphaneity make it useful as a gemstone and also in the making of glass. Chemical formula :- SiO2 Application : Different forms are also used as gemstones. Because it is a primary ingredient in sand it is also used to make glass & labware, silica brick, cement, and mortar. Ground quartz is used as an abrasive in stonecutting, sandblasting, and glass grinding. Powdered quartz is used in making porcelain, scouring soaps, sandpaper, and wood fillers.

Reaction of silica with lead oxide or sodium oxide is utilized to produce different grades of glass that includes borosilicate glass. It is used as one of the key ingredients for micro chip in computer. It acts as an additive for processing of plastics and rubber. It is used as a powerful filler for producing construction material like concrete. It is used for improving viscosity of coatings. Useful for enhancing holding capacity of tire on wet surface.
