High Light 0.3um Calcined Alumina PowderCalcined Alumina Powder 9mohsPolishing Calcined Alumina Powder
0.1-0.3µm Calcined Alumina Powder | 9 Mohs High Hardness for Precision Polishing
Our Calcined Alumina Powder is engineered for precision polishing applications where surface quality is critical. With a controlled particle size of 0.1-0.3 micrometers and exceptional 9 Mohs hardness, this premium alumina powder delivers outstanding polishing performance for the most demanding industrial applications.
Key Product Advantages
  • Exceptional Hardness - 9 Mohs hardness ensures effective material removal and superior surface finishing
  • Narrow Particle Distribution - Controlled 0.1-0.3µm size range guarantees consistent, scratch-free results
  • Excellent Suspension Stability - Maintains uniform dispersion in polishing compounds and slurries
  • Optimized Crystal Morphology - Round-shaped crystal structure prevents surface damage and enables fine polishing
  • High Purity Composition - Minimum 99.2% Al₂O₃ content ensures reliable, contaminant-free performance
