For Fireproof Materials Low Thermal Expansion Coefficient Chemically Stable Quartz Sand

Product Description

Quartz sand is a kind of hard, wear-resistant and chemically stable silicate mineral. Its main mineral composition is SiO2. The color of quartz sand is milky white or colorless translucent, with a hardness of 7.It is brittle, cleavage-free, shell-like fracture, grease gloss, density 2.65, packing density (1.6-1.8 in 1-20 mesh ) is 1.5 in 20-200 mesh. Its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750℃.

Application

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

Main Features 

Quartz sand has unique physical and chemical characteristics, which make it play an important role in the aviation, aerospace, electronics, machinery and today's rapidly developing IT industry. Especially its internal molecular chain structure, crystal shape and lattice change rule make it have high temperature resistance, low thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical characteristics, which play an increasingly important role in many high-tech products.

The common specifications of quartz sand are: 0.5-1 mm, 1-2 mm, 2-4 mm, 4-8 mm, 8-16 mm, 16-32 mm, 10-20 mesh, 20-40 mesh, 40-80 mesh and 100-120 mesh.
