Quarts Sand
The quartz is the most common mineral which alone forms by SiO2 in the nature, which including two kinds of quartz, one is trigonal crystal low temperature quartz (α quartz) and hexad crystal high temperature quartz (β quartz). The common major part is the low temperature quartz, generally is called the quartz. Its assumes the shapes of rhombohedron, hexad direction columniation, double tripartite cone, the tripartite rhombic shape; which color is achromaticity, ivory-white, multi-colors if mixed in the impurity; Not cleaves, has the conchoidal fracture, the oily luster; hardness 7, density 2.65g/cm3. Its crystal common has solid, liquid and gas enwrap.
The quartz sand is one kind of minerals name, which including the many kinds. The hyaline-quartz is refers to the nature mineral or rock which ore ingredient and granularity conforms to the glass industry requested. In the ore mineral ingredient, the quartz is primary and the secondary mineral has each kind of feldspar,the rock debris, weightily mineral(pyrope, tourmaline, pyroxene, hornblende, fine stone, topaz, epidote, ilmenite and so on) as well as the mica, the green mudstone and the clay mineral and so on. The quartz placer may divide into the quartz sand, contain the feldspar clay quartz sand, contains ore type and so on feldspar quartz sand, general designation the mineral of sand; Thesilicarenite, the aposandstone and matrix quartz are called as the crag class ore.
Chemistry component:
Ingredient SiO2 Al2O3 Fe2O3 CaO Na2O
Content 99.6% 200ppm 50ppm 30ppm 30ppm
Main use:
Quartz sand is important raw materials of industrial mineral, used extensively in such as glass, casting, pottery and refractory material, metallurgy, architecture, chemical industry, plastics, rubber, abradant material and so on.
Glass: Plate glass, float glass, glass products (Glass tube, glass bottle, glass pot) optical glass, glass fibre, glass instrument, conductive glass, glass cloth and the special glass of defending radial , ect.. the main pottery porcelain and refractory fire material; Embryo material and frit of the porcelain, the cellar stove uses the raw materials such as high silica brick, ordinary silica brick and carborundum, etc..
Metallurgy: The raw materials, additives or flux of silicon metal, silicon ferroalloy and silicon aluminium alloy,etc
Building: Concrete, glue congeal material, build the road material, artificial marble, examining materials of cement physical performance (i.e. cement standard sand),etc.
Chemical industry: Raw materials of silicon compound and water glass,etc., the filler in the sulfuric acid tower, amorphism silicon dioxide and tiny powder.
Machinery: The main raw materials of cast molding sand, grind materials (gush out the sand, grind the paper, abrasive paper, emery cloth etc.).
Electron: Metal silicon of high strength, use the optic fibre in communication,etc.. Rubber, plastics (can improve the wearability).
Coating: Filling (but improvement coating is weatherable).
