Wet-jet milling process was employed to modify the properties of Al2O3 slurry after ball milling. Particle size distribution of slurry wet-jet milled after ball milling corresponded to that of ball-milled slurry. However, the viscosity of ball-milled slurry increased rapidly with time, whereas the viscosity of the slurry wet-jet milled after ball milling was stable for long times. Al2O3 particles after ball milling yielded more OH groups on the surface. These OH groups were reduced or removed by wet-jet milling following ball milling. Moreover, wet-jet milled slurry after ball milling had lower re-flocculation properties and higher packing density of above 60% than ball-milled slurry. Hence, Al2O3 particles in slurry wet-jet milled after ball milling is packed well as compared to ones of ball-milled slurry before wet-jet milling treatment.
