5N High-purity Super-fine Alumina


Taking high quality alumina from CHALCO Shandong as raw material, ultra-fine mono-disperse precursor was synthesized by synergistic action of nucleating agent and growth inhibitor. Then the template agent was introduced to finalize the shape of nano-alumina crystal. After all these, 5N high purity ultra-fine alumina were produced.


Application:High-purity alumina grinding beads/Transparent Ceramics/Alumina nitride/Precising polishing
