✦ Synopsis

The effects of the final aspect ratio on the overall shape of cylindrical sintered compacts, prepared by a uniaxial die pressing technique, are measured and described. An empirical compaction equation, which describes the compaction behaviour of a spray dried AKP-30 alumina powder, is presented. The density distribution along the axis of the compacts was predicted by using an established first-order analysis. From these predicted density distributions, the overall shapes of the sintered compacts were quite accurately predicted by using a set of sintering simulation equations obtained in separate experiments.
