| Abstract: | 0.62Bi(Mg1/2Ti1/2)O3-0.38PbTiO3-xwt%Bi2O3 (BMT-0.38PT-xBi2O3) ceramics were prepared by conventional powder-processing method. It indicated that the morphotropic phase boundary (MPB) region located in 0.0?≤?x?≤?0.3. For x?=?0.3, it exhibited good piezoelectric properties, d33 ~245pC/N and kp ~40 %. With the increase of Bi2O3 content, the Curie temperature (Tc) was found to increase, and the dielectric loss was found to decrease above 200 °C compared with BMT-0.38PT sample. Finally, it can be found that depolarization temperature was around 350 °C by thermal depoling method. |
