Abstract

0. 8PMN-0. 2PT powders and ceramics of pure perovskite were sucessfully prepared by molten salt synthesis using mixtures of NaCl and KCl salt. The effect of excess PbO and excess MgO on phase structure and dielectric property of PMN-PT ceramics was studied. The results indicate that excess PbO and excess MgO have a beneficial effect on reducing and even eliminating py-rochlore phase and increasing dielectric constant. The effect of excess MgO is better than that of excess PbO.
