A clear understanding of the true nature of the quartz

Quartz is a kind of physical properties and chemical properties are very stable mineral resources, crystallizes in the trigonal crystal system of oxide minerals, namely, low temperature quartz (alpha quartz), is most widely distributed family of quartz mineral of a mineral species. Quartz block, also known as silica, mainly raw materials for production of quartz sand (sand), and silica refractory materials and ferrosilicon firing of raw materials. Quartz chemical formula is SiO2, the main component of natural quartz is quartz, often containing a small amount of impurities such as Al2O3, IMO, CaO, MgO, etc.. Quartz can be divided into ordinary quartz sand, quartz sand, quartz sand, fused silica sand.
