1. Ordinary quartz sand
Ordinary quartz sand, i.e. SiO2 ≥ 90-99%, Fe2O3 ≤ 0.06-0.02%, fire resistance 1750 ℃, appearance: some large particles have yellow skin cysts on the surface. Ordinary quartz sand is generally a water treatment filter material made of natural quartz ore through crushing, washing, drying and secondary screening; This filter material has the characteristics of no impurities, no edges, high density, high mechanical strength, and long service life of the pollutant carrying capacity line, making it an ideal material for chemical water treatment. The particle size range is 5-220 mesh, which can be produced according to user requirements. Main uses: metallurgy, graphite silicon carbide, glass and glass products, enamel, cast steel, water filtration, bubble alkali, chemical, spray noise and other industries.
2. Refined quartz sand
Also known as acid washed quartz sand, SiO2 ≥ 99-99.5%, Fe2O3 ≤ 0.005%, high-quality natural quartz sand and mortar are used.
3. High purity quartz sand
SiO2 ≥ 99.5-99.9%, Fe2O3 ≤ 0.001%, using high-quality natural quartz stone and mortar. (mm in millimeters)
4. Fused silica sand
Chemical composition: SiO299.9-99.95%, Fe2O35PPM-25PPMmax, Li2O1-2PPMmax, Al2O320-30PPMmax, K2O20-25PPMmax, Na2O10-20PPMmax (PPM in parts per million units).
