Summary

Isostatic hot pressing as a means of postsintering processing ceramics is presented. The density of sintered lead zirconate titanate increases from 93 to 96% of theoretical when pressed at 6.9 Mpa and 1300°C for 15 min. Rapid initial kinetics and preferential shrinkage of macropores indicates that densification occurs by plastic deformation. Intragranular cracking, persistence of microporosity, and reduced kinetics suggest that strain hardening and/or internal pore pressure retard densification after the first 15 min of pressing.
