Quartz products are the main raw materials for high-purity quartz sand and fused silica sand, the main physical and chemical properties are as follows:
High purity quartz sand: SiO2 ≥ 99.5-99.9% Fe2O2 ≤ 0.005%, is the use of 1-3 natural crystal stone and high-quality natural stone, after careful selection, fine processing from Particle size range of 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user requirements.
Fused silica sand: Chemical composition:
SiO2 99.9-99.95% Fe2O3 5PPM-25PPM max Li2O 1-2PPM max Al2O3 20-30PPM max
K2O 20-25PPM max Na2O 10-20PPM max (PPM is one millionth of a unit)
Appearance is colorless and transparent lumps, granules or white powder.
