| Abstract: | PMN-PT piezoelectric ceramics in the vicinity of the morphotropic phase boundary were obtained by molten salt synthesis, and its piezoelectric and dielectric properties were studied. The results indicate that the dielectric constant reaches the peak value near the morphotropic phase boundary. The piezoelectric properties of PMN-PT ceramics prepared by molten_salt method are better than those prepared by conventional ceramics processing. In molten salt method, K p=58%, d 33 =520pC/N; but in the latter K p=46%, d 33 =367pC/N. |
