Quartz is one of the main rock-forming minerals, generally refers to low-temperature quartz (α-quartz), which is the most widely distributed mineral in the quartz group. The generalized quartz also includes high-temperature quartz (β-quartz) and cogite. The main component is SiO2, colorless and transparent, often contains a small amount of impurities, and become translucent or opaque crystals, hard texture.
Quartz is a kind of physical and chemical properties are very stable mineral resources, the crystal belongs to the trigonal system of oxide minerals. Quartz, also known as silica, is mainly the raw material for the production of quartz sand (also known as silica sand), and is also the raw material for quartz refractory materials and ferrosilicon.
Quartz is a mineral composed of silica, chemical formula SiO2. Pure quartz is colorless and transparent, with trace pigment ions or finely dispersed inclusions, or the existence of color center and a variety of colors, and reduce the transparency. It has glass luster, and the fracture is grease luster. Hardness 7, no cleavage, shell-shaped fracture. Specific gravity 2.65. Piezoelectricity.
Colorless, transparent quartz, the Greeks called "Krystallos", meaning "white ice", they are convinced that quartz is durable and strong ice. Ancient Chinese people believed that cold crystals in their mouths could quench thirst.
On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization preliminary collation reference, quartz or cristobalite form of crystalline silicon dust in the list of a class of carcinogens.
