Quartz Grits

Quartz Grits from Pakistan

Quartz grits are premium-grade crushed quartz produced by milling and sizing high-purity quartz sand or quartzite. The combination of hardness, high SiO₂ content, chemical inertness, light color, and controlled particle shape and size make quartz grits a superior choice for many industrial and functional applications. Pakistan’s quartz deposits are among the purest in the region, yielding quartz grits with SiO₂ levels above 98%.

Typical Composition

• SiO₂: 98-99.5%

• Fe₂O₃: 0.02-0.2%

• Al₂O₃: 0.1-0.8%

• TiO₂: < 0.05%

• CaO + MgO: < 0.1%

• Na₂O + K₂O: < 0.2%

• LOI: < 0.3%

Standard Sizes (Mesh)

• 8/16 (2.36-1.18 mm)

• 16/30 (1.18-0.6 mm)

• 30/50 (0.6-0.3 mm)

• 50/80 (0.3-0.18 mm)

• 80/100 (0.18-0.15 mm)

Other standard and customized mesh sizes can be produced on request.
