Description
Innovacera Silicon Nitride Grinding Media Balls was made by 3 forming ways: titration, roll and CIP (cold isostatic pressing ) forming and they were gas pressing sintering in 1800～2100℃.
The purity of silicon nitride is 99%, and generally, if the diameter is more than 3mm, we will choose the CIP forming method.
Silicon nitride grinding balls have excellent features of chemical inertness, low friction and heat generation, electrical insulation, non-magnetic, high strength and corrosion resistance.
Compared with other grinding media, the silicon nitride milling media balls improves energy efficiency, reduces mechanical wear and ultra-fine grinding and dispersion. It is a ideal grinding media when high wear resistance, minimal contamination and less abrasion is required such as semiconductor slurries, pharmaceutical dispersions, battery material milling. Our silicon nitride media balls main size is 0.2 mm – 20 mm .
