Product introduction:
3N High purity Quartz sand silica 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℃.
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.
