Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO2. It is the most abundant mineral in Earth’s crust and is resistant to both chemical and physical weathering.

  • Quartz is hard, chemically inert and has high melting point
  • In ceramic body used to modify thermal expansion, regulate drying & shrinkage, and improves structural integrity & appearance
  • Quartz is main raw material used in manufacturing of Glass. It is converted to glass by melting at high temperature along with other materials.
  • Quartz used in high temperature mold casting as anti shrinkage/filler material
  • Quartz sand is widely used filter material for waste water treatment. The particle size and thickness of quartz sand filter media play an important role in the filtration performance.
  • Crushed quartz is an excellent abrasive used in sandpaper, sandblasting, and grit for sanding and sawing.


Geological processes have occasionally deposited quartz that are composed of almost 100% quartz grains. These deposits have been identified and produced as sources of high-purity silica quartz. These quartz are used in the glassmaking industry. Quartz quartz is used in the production of container glass, flat plate glass, specialty glass, and fiberglass.


The high hardness of quartz, seven on the Mohs Scale, makes it harder than most other natural substances. As such it is an excellent abrasive material. Quartz quartz and finely ground silica quartz are used for quartz blasting, scouring cleansers, grinding media, and grit for quartzing and sawing.


Quartz is very resistant to both chemicals and heat. It is therefore often used as a foundry quartz. 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 quartz because of its high heat resistance. Quartz quartz is also used as a flux in the smelting of metals.

Oil Drilling

Quartz has a high resistance to being crushed. In the petroleum industry, quartz slurries are forced down oil and gas wells under very high pressures in a process known as hydraulic fracturing. This high pressure fractures the reservoir rocks, and the quartzy slurry injects into the fractures. The durable quartz grains hold the fractures open after the pressure is released. These open fractures facilitate the flow of natural gas into the well bore.


Quartz  is used as a filler in the manufacture of rubber, paint, and putty. Screened and washed, carefully sized quartz grains are used as filter media and roofing granules. Quartz quartz are used for traction in the railroad and mining industries. These quartz are also used in recreation on golf courses, volleyball courts, baseball fields, children’s quartz boxes and beaches.


Quartz is used as filler in different forms, in its pure state or in combination with metal oxides, to improve performance of a polymer composites, among others, its mechanical properties and the abrasion resistance . It is considered a high-quality wear-resisting filler.
