Abstract
A process and products produced thereby, e.g., alumina tools, in which ceramic powder particles are subjected to high transmissive energy milling under dry conditions and with given ratios of impacting media to powder, the milling being conducted for a period beyond the threshold point of the powder constituents, whereby dense, composite powder particles are obtained having an interdispersion of initial constituent particles, a large internal interfacial surface within individual product powder particles, etc.
