White quartz, three fractions

Low-iron, sub-angular quartz from Türkiye, the largest foreign source of quartz for U.S. manufacturers. Fine, medium and coarse fractions from 63 µm to 2.5 mm, supplied by the container or in bulk against an agreed specification.

Fine

63–212 µm · approx. 70–230 mesh

Powder-range quartz for fillers, coatings and fine mixes. SiO₂ 99.00% minimum.

Medium

300–700 µm · approx. 25–50 mesh

Sand-range grit with very low iron: Fe₂O₃ between 0.005 and 0.015%.

Coarse

1200–2500 µm · approx. 8–16 mesh

Granule-range quartz with the lowest iron of the three: Fe₂O₃ 0.010% at most.
