The effect of Ag and PbO on the sintering behavior and the piezoelectric properties of PbSr(Mg<SUB>1/3</SUB>Nb<SUB>2/3</SUB>)O<SUB>3</SUB>-PbZrO<SUB>3</SUB>-PbTiO<SUB>3</SUB> system has been studied. A small addition of Ag enhances the value of εr. and Kr. In the specimen with Ag addition, the grain growth was observed by use of SEM. The shrinkage vs temperature curves showed that the shrinkage of the specimen with Ag addition abruptly increases from 900°C and the value of shrinkage at 1100°C is as twice as the additive-free specimen. The shrinkage vs time plots revealed that the grain boundary diffusion is dominant on the sintering of PMN-PZT with Ag and Pb addition.
