分别对0.3BaTiO_3 <$0.1Bi（Mg_（1/2）Ti_（1/2））O_3 <$0.6BiFe_（3）陶瓷进行了钒掺杂和相同成分的烧结。与未掺杂的陶瓷相比，两种陶瓷都显示出降低的漏电流密度（低于1 © 1017 A/cm 2），并且在频率和温度依赖的介电测量中观察到没有介电弛豫行为。两种样品的居里温度均高于460°C。最大场致应变超过所施加的场，Smax/Emax，为366 pm/V的未掺杂的陶瓷烧结没有煅烧的粉末增加到455和799 pm/V的V掺杂的样品和样品烧结与煅烧的粉末，分别。讨论了铋空位和氧空位缺陷偶极子浓度降低时的增加。
0.3BaTiO30.1Bi(Mg1/2Ti1/2)O30.6BiFeO3 ceramics were either doped with vanadium or sintered in calcined powder with the same composition. Compared to an undoped ceramic sintered without the calcined powder, both ceramics showed reduced leakage current densities (lower than 1 © 1017 A/cm2) and absence of dielectric relaxation behaviors observed in frequencyand temperature-dependent dielectric measurements. The Curie temperatures of both samples were higher than 460°C. The maximum field-induced strain over the applied field, Smax/Emax, of 366 pm/V for the undoped ceramic sintered without the calcined powder increased to 455 and 799pm/V for the V-doped sample and the sample sintered with the calcined powder, respectively. The increase was discussed with reduced concentrations of bismuth vacancyoxygen vacancy defect dipoles.
