Quartz, geology terminology, one of the major rock-forming minerals, generally refers to low-temperature quartz (α-quartz), is the most widely distributed mineral minerals in quartz. Generalized quartz also includes high temperature quartz (β-quartz), Ke Shiying and so on. [1] the main component is SiO2, colorless and transparent, often contain a small amount of impurity composition, and become translucent or opaque crystal, hard texture. Quartz is a physical property and chemical properties are very stable mineral resources, crystal is a triad of oxide minerals. [2] quartz block, also known as silica, mainly the production of quartz sand [3] (also known as silica sand) of raw materials, but also quartz refractory materials and ferrosilicon raw materials.

    A mineral composed of silica, a chemical formula of SiO2. Pure quartz colorless and transparent, due to trace of pigment ions or fine dispersion of inclusions, or the presence of color and was a variety of colors, and reduce the transparency; glass luster, fracture was grease shiny. Hardness 7; no cleavage; shell-like fracture. Specific gravity 2.65. With piezoelectricity. [1] Colorless, transparent quartz, the Greeks called "Krystallos", meaning "white ice", they are sure that quartz is durable and sturdy ice. Ancient Chinese people think that the mouth with cold crystals can quench thirst.
