LOW-SODIUM WHITE CORUNDUM

Low-Sodium White Corundum is a high-purity abrasive material made from high-quality alumina with strictly controlled sodium content. Compared with standard white corundum, it offers lower Na₂O levels, high Al₂O₃ purity, and consistent particle characteristics, making it suitable for applications where material purity and stable processing performance are important.

With Al₂O₃ typically ≥99.6% and Na₂O controlled to ≤0.10%, Low-Sodium White Corundum provides excellent hardness, thermal stability, and abrasive performance. Ultra-low sodium grades can be supplied with Na₂O as low as approximately 0.05% according to specific requirements. It is available in fine grit and micropowder grades, with controlled particle size distribution for grinding, lapping, polishing, and precision surface finishing.
