Polycrystalline Alumina

Polycrystalline Alumina
A pioneer in the development of seeded gel abrasives, Saint-Gobain offers high-performance polycrystalline alumina particles for a variety of polishing applications.
Our groundbreaking technology produces a grain with a unique nano-structure composed of extremely uniform, sub-micron crystals. Under stress, the nano-structured crystal network allows micro-fracturing, continually exposing new cutting edges that keep the particle sharper than conventional abrasives for longer-lasting abrasive performance.
Saint-Gobain will recommend the best-performing particle for your application or work side-by-side with you to develop a positive interaction in your formulations. We offer polycrystalline alumina particles in aqueous form with a pH from basic to acidic, particle sizes from 100nm to 2um, and solids loadings from 20% to 45%.
