Silicon Nitride is one of the hardest substances in the world. Its wear resistance and high temperature resistance properties make it the best suitable material as grinding balls/beads for high purity powders grindings.

Higher grinding efficiencySilicon-nitride media have a Vickers hardness of 14–18 GPa, versus 10–13 GPa for zirconia. The higher hardness of silicon nitride delivers faster size reduction and higher throughput.

Extremely low wear (10ppm)The 24-hour wear rate of silicon-nitride media is only 10ppm—effectively zero. This negligible wear reduces contamination of the product, enabling higher-purity ultra-fine powders and eliminating concerns over imp ...
