Quartz sand has a higher fire resistance, quartz sand will often divided into: ordinary quartz sand, refined quartz sand, high purity quartz sand, fused silica sand and silica powder, etc..
1 ordinary quartz sand
Ordinary quartz sand SiO2 ≥ 90-99% Fe2O3 ≤ 0.06-0.02% Refractoriness 1750 ° C, the appearance of some of the large particles, surface yellow cysts. 5-220 mesh size range, users can request the the granularity production. Main purpose: metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, water filtration, sodium silicate, chemical spray noisy industry.
2. Refined quartz sand
Refined quartz sand, also known as pickling quartz sand, SiO2 ≥ 99-99.5% Fe2O3 ≤ 0.02-0.015%, complex processed from selected high-quality ore. Size range 5-480 mesh, users can request the production, the appearance of white or crystalline. Main purposes: Advanced glass and glass products, refractories, smelting stone class, precision casting, grinding wheel and other materials. (Mm mm)
3 high purity quartz sand
High purity quartz sand SiO2 ≥ 99.5-99.9% Fe2O3 ≤ 0.005% 1-3 grade natural crystal stone and high quality natural stone class, carefully selected, fine processing. The size range of 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user requirements. (Mm mm)
Fused silica sand
Chemical Composition: SiO2 99.9-99.95% Fe2O3 5PPM-25PPM max Properties of Li2O-2PPM max Al2O3 20-30PPM max K2O 20-25PPM max of Na2O 10-20PPM max (PPM millionth unit) Physical properties: Appearance colorless transparent massive, particles or a white powder. Relative weightings: 2.21; Mohs hardness: 7.0; PH value: 6.0;
Quartz manufacture of glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasives, foundry, quartz stone in strong acid medium erosion ability to use its building, used for extracting the the concrete acid and acid-resistant mortar .
