Quartz, inorganic minerals, the main component is silica, often containing a small amount of impurities such as Al2O3, CaO, MgO, etc., is a translucent or opaque crystal, generally milky white, hard texture. Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the trigonal oxide mineral, ie low-temperature quartz (a-quartz), which is the most widely distributed mineral species in the quartz family. The generalized quartz also includes high temperature quartz (b-quartz). Quartz block, also known as silica, is mainly used to produce quartz sand (also known as silica sand), and is also a raw material for quartz refractories and fired ferrosilicon. In addition, "quartz" is also a more common name.
