How many kinds of quartz sand raw materials?

Quartz sand is the quartz particles of crushed quartz stone. Quartz stone is a kind of non-metallic minerals, is a hard, wear-resistant, stable chemical properties of silicate minerals, its main mineral composition is SiO2. The color of quartz sand is milky white, colorless translucent, mohs hardness 7.

Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramic fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastic, rubber, abrasive, filter material other industries.

Quartz ore is usually divided into quartz, squamous quartz, silica three categories. Uncemented crushed rock consisting essentially of quartz grains is called quartz sand. Quartz includes tripartite low temperature quartz (α - quartz) hexagonal high temperature quartz (β - quartz), generally referred to as quartz refers to low temperature quartz. As an industrial raw material, quartz can be divided into piezoelectric quartz, optical quartz, fused quartz polished quartz according to its quality use.

Quartz is a mineral resource with very stable physical chemical properties. The crystal belongs to tripartite oxide minerals, namely low-temperature quartz (A-quartz), which is a widely distributed mineral species in the Quartz family. The broad term quartz also includes high temperature quartz (B-quartz). Quartz block, also known as silica, is mainly the production of quartz sand (also known as silica sand) of raw materials, but also quartz refractories burning iron silicon raw materials. Quartz chemical formula Si02, often contains a small amount of impurities such as A1203, IMO, CaO, Mg0 so on. There are many types of it, including gangue quartz, quartz sand, quartzite, sandstone, silica, opal, diatomite so on.
