Quartz	Quartz

    Low-temperature quartz appearing with steeple of the six-party columnar crystals outputs, a cylindrical stripes and similar to the six-party-ubiquitous steeple, in fact, consist of two single rhombohedral-shaped body formed. Quartz is usually granular aggregates, massive or DRUSE, crystal and other glands. Pure transparent colorless quartz, glass, shiny, magma fracture, with the oil sheen, no cleavage, Moldova's hardness of 7, the proportion of 2.65. Pressure or heat can produce electric effect.

    Quartz by size, color, inclusions, etc. There are many different varieties. Colorless and transparent as quartz crystal, crystal commonly known as Amethyst purple, yellow smoke, tobacco brown to nearly black, commonly known as Chajing. Breathing or MO Jing - Jing, commonly known as the Red Rose ROSE QUARTZ; Kidney was accused of, the bell emulsion cryptocrystalline quartz stone myeloid said, with a different color bands concentric crystal structure of adenovirus called agate, agate crystal gland within the visible liquid inclusions of water, commonly known as agate guts, Microcrystalline composed of fine-grained gray to black cryptocrystalline quartz known as chert, commonly known as Flint.

    Quartz uses quite extensive. No fissures, and the crystal defect-free crystal piezoelectric materials used to manufacture quartz resonators and filters. General quartz glass can be used as raw materials, purple, pink quartz and agate sculpture can be made arts and crafts materials.

    Quartz is the most important rock-forming minerals in one of igneous, sedimentary, metamorphic rocks are distributed widely. 

I plant specialized in the production of quartz sand / powder Quartz sand on the nature and structure：     Silica sand is a hard, abrasion resistance, chemical stability of silicate minerals, the main mineral component of SiO2, quartz sand color for the translucent milky white or colorless - hardness 7, brittle no cleavage, magma fracture, oil sheen, the relative density of 2.65, its chemical, thermal and mechanical properties have obvious anisotropy, do not dissolve in acid, Micro-soluble KOH solution, the melting point of 1750 ℃. Quartz sand Quartz powder     Production of the plant quartzite and quartz sand, according to the quality can be divided into ordinary quartz sand, quartz sand refined specially refining quartz sand. Quartz sand to the use and role : Silica sand is an important industrial mineral raw materials, widely used in glass, foundry, ceramics and refractories, metallurgy, construction, petrochemicals, plastics, rubber, and other industrial abrasive.   Physicochemical standards Clay content Refractoriness Size composition Ordinary sand stone Fe2o3<0.03% 0.05%   Head ranging from 20-400 The nicety casts sand sio2>99.3% 0.05% 1750 degree 20 － 400 eyes don't wait Construct sand sio2>99.3% 0.05%   3 － 30 eyes don't wait     Silica sand powder：The quartz is a kind of physical property and the all very stable mineral resources of the chemistry property, the chemistry composition of quartz is a SiO2, the crystal belongs to three squares crystal fasten of oxide mineral, namely the low temperature quartz(a-quartz) be a quartz clan to distribute a most wide mineral to grow in the mineral.Broadly speaking does the quartz still include heat quartz(b-quartz).Quartz piece again the Huo stone be mainly the raw material which produces silica sand(call silica sand again), is also quartz fire-proof material and burn to make a Huo iron of raw material.Quartz sandstone, the main composition is a quartz, the density is an each square Li the rice be 2.65 grams, Mo surname degree of hardness is 7, the crystallize belongs to 60,000 crystals to fasten, the external appearance becomes white, green gray, grey color etc..Mainly used for glass ware, cast industry, metallurgy industry, the porcelain and ceramics uranium noodles, fire-proof material, cement industry, chemistry industry etc..
