1.made from natural high quality crystal stone
2.high content of SiO2
3.low impurity
Quartz sand (powder) is mainly applied in the industries of glass, water treatment filtration,
exact foundry, refractory, ceramic, casting, printing, dyeing, quartz melting, petroleum,
chemical, abrasive, etc,
Silicon content is very high and very low iron, sodium, chloride, silica content of 99.9%,alumina 300ppm, 20ppm iron as the largest and magnesium oxide for the 10ppm maximum.we can supply different sizes quartz grain,welcome to contact us for the further details.
