A fast firing technique for densification of PZT (up to 97% of theoretical density) at a low temperature (950 degrees C) has been found out. A small amount of excess PbO (3-5 wt.%) and a fast firing schedule are required to achieve the desired sintering. The final composition of the sintered ceramics can be kept close to the morphorropic phase boundary by modifying the firing time and post-sintering annealing treatment at 800 degrees C. The g(33) values of fast fired samples are comparable to those of conventionally sintered samples, though the d(33) values are somewhat lower than those reported for conventionally sintered (at 1250'C or above) samples
