Quartz is the most abundant mineral in the Earth’s continental crust. 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 (silicon dioxide, SiO2), with a hardness of 7 on the Mohs scale. This is used as a basic raw material for the Ceramic, Fiber glass, Paint, Epoxy making Industry etc.Quartz Sand or Quartz Powder is manufactured by crushing crystalline quartz lumps to various sizes and is also known as white silica sand. Quartz Sand has very high silica content as compared to river sand and has negligible or no natural impurities. Quartz Sand is highly resistant to both mechanical and chemical weathering and makes an excellent filter media. When quartz lumps are grounded to the size of 2-3 mm stones, they are colloquially known as silex.
