Polycrystalline Alumina Polishing Slurry, 9240 and 9245

Product Codes: 9240 and 9245

Saint-Gobain Ceramic Materials' Polycrystalline Alumina Polishing Slurry is an aqueous slurry of alumina in which the fundamental crystal size ranges from 50 to 100 Nano Slurries, 9240nanometers.   The unique composition of extremely small crystals, primarily alpha alumina, results in an extremely cost-effective, rapid polishing slurry that will achieve highly polished finishes on most materials.


Polycrystalline alumina slurry is effective over an extremely broad range of metals, crystals and ceramics.  This product can be used with pads, pitch or metal plates and is available in either an acidic or basic solution.



Polycrystalline alumina slurry shows best results on:

  • Ceramics
  • C-plane sapphire
  • Ferrous metals
  • Aluminum
  • Other metals
  • High purity alpha Al2O3 slurries
  • Readily available in commercial quantities
