Abstract
Pure perovskite phase of PZN-PZT solid solution near morphotropic phase bou ndary (MPB) has been prepared by conventional electric ceramic engineering. The Zr/Ti ratio of the MPB of PZN-PZT solid solution is about 37/33. The f erroelectric-to-relaxor-paraelectric phase transition of PZN-PZT solid solu tion near MPB has been identified when the sample is heated. In addition, t he transition from rhombohedral to tetragonal has been found for the poled samples with Zr/Ti ratio to be 37/33 and 39/31. It is believed that the MPB of PZN-PZT bends toward Zr-rich region.
