High pure white quartz sand

Kojun Shiraishiyingsa level: SiO2 is more than 99.90%; Fe2O3 is less than 0.017%, 20-60 mesh 20-90 mesh pure white material. Kojun Shiraishiyingsa mainly applies to: white white wine bottles, medicinal glass bottles, high white canned bottles, high white flat glass, perfume bottles, etc.
Kojun Shiraishiyingsa two: SiO2 > 99.80%; Fe2O3 less than 0.023% 20-120 eyes high white material of white material is mainly suitable for: high white wine bottle, beer bottle, white canned bottle, plain flat glass, refractory brick material and so on.
Kojun Shiraishiyingsa grade three: SiO2 is more than 99.60%; Fe2O3 is less than 0.023%, 60-240 Mu Pu fine powder Kojun Shiraishiyingsa is mainly applied to: ceramics.
Kojun Shiraishiyingsa four level: SiO2 > 99.80%; Fe2O3 less than 0.023% 240-560-1000 mesh high white superfine powder Kojun Shiraishiyingsa is mainly suitable for: epoxy resin pouring, sealing, plastic sealing material and so on.
Kojun Shiraishiyingsa is a hard, wear-resistant, chemically stable silicate mineral whose main mineral composition is SiO2. The color of quartz sand is milky white or colorless translucent, with a hardness of 7, brittle and uncleavage, shell shaped fracture, oil luster, and relative density of 2.65, and its chemical, thermal and mechanical properties are obvious. It is insoluble in acid, slightly soluble in KOH solution, and melting point is 1750 degrees. The color is milky white, yellowish, brown and gray, quartz has high fire resistance, divided into: ordinary quartz sand, refined quartz sand, acid washing quartz sand, high pure quartz sand and so on.
Kojun Shiraishiyingsa's unique physical and chemical properties make it play an important role in the aviation, space, electronics, machinery and the rapid development of the IT industry, especially its internal molecular chain structure, crystal shape and lattice change law, so that it has high temperature resistance, low thermal expansion coefficient and high coefficient. Degree insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical characteristics play an increasingly important role in many high-tech products.
