Wet ball milling was studied as a method of reducing highly aggregated alumina powders to an ultimate particle condition. The particulate structures in powders milled by various methods were determined by electron microscope examination and correlated with changes in compaction behavior, sinterability and microstructural uniformity of sintered compacts. Denser aggregates were formed in the wet-milled aluminas. These powders showed improved compaction behavior but sinter ability was reduced. Various experimental methods were used to wash the wet-milled powders. Optimum treatments yielded powders containing no dense aggregates and which showed improved processing behavior.
