Abstract

La³⁺⁃doped 0.28Pb(In_1/2Nb_1/2)O₃⁃0.32Pb(Zn_1/3Nb_2/3)O₃⁃0.3PbTiO₃⁃0.1PbZrO₃ (PIN⁃PZN⁃PZT) quaternary piezoelectric ceramics were prepared by the conventional solid⁃phase method, and the effects of La³⁺ doping on the microstructures and electrical performances of PIN⁃PZN⁃PZT quaternary piezoelectric ceramics were investigated. The results show that introducing La³⁺ can enhance the local structural heterogeneity of piezoelectric ceramics, enhancing the dielectric relaxation properties to improve the piezoelectric performance. When the La₂O₃ content was 1.5%, piezoelectric ceramic materials with high electrically induced strain (0.23%) and high Curie temperature (206 ℃) were obtained.
