Hebei quartz sand

Quartz sand is a hard, wear-resistant, chemical stability of silicate minerals, the main mineral component is SiO2, quartz sand color is white or colorless, translucent, hardness 7, no cleavage of brittle, conchoidal fracture, oil sheen, and the relative density of 2.65, its chemical, thermal and mechanical properties have obvious anisotropy, and do not dissolve in acid, slightly soluble in KOH solution, melting point 1750 ℃. The color is milky white, yellow, brown and gray, quartz has a higher fire resistance. Quartz sand by the unique physical and chemical properties, making it in the aviation, aerospace, electronic, mechanical, and the rapid development of today's IT industry occupies a pivotal position, in particular its intrinsic molecular chain structure, changes of crystal shape and lattice , it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, the piezoelectric effect, resonance effect and its unique optical properties, in many high-tech products is playing an increasingly important role.

The use of quartz sand: the manufacture of glass, refractories, smelting ferrosilicon, metallurgical fluxes, ceramics, abrasive materials, casting, the quartz in the building to use its strong acid etching medium capacity, used for extracting acid and acid-resistant concrete mortar. Quartz sand as the core of silicon raw materials in production and supply of silicon raw materials played an important basis for those irreplaceable role.

The main specifications of quartz sand :6-8mm ,4-6mm ,10-20 mesh ,20-40 mesh ,40-80 mesh ,80-120 ,140-160 mesh and other projects.
