Porous Zr‐rich lead zirconate titanate (PZT 95/5) ceramics having 77.9–92.2% of relative densities were prepared without additional pore formers. PZT 95/5 powders were obtained by a one‐step pyrolysis process at 450°C for 10 h using the Pechini method. Although the X‐ray diffractometry results showed an incomplete perovskite phase for the powders, phase‐pure PZT 95/5 ceramics could be obtained after sintering at 1100°–1150°C for 2 h. The density and diameter variations of the PZT 95/5 ceramics as a function of sintering temperature were investigated.
