【 摘 要 】

xPb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3(xPIN–yPMN–zPT) ternary ceramics with morphotropic phase boundary (MPB) composition were synthesized by columbite precursor method. xPIN–yPMN–zPT phase diagram was investigated by x-ray diffraction and dielectric measurements. According to the results of dielectric measurements, the Curie temperatures (Tc) and rhombohedral to tetragonal phase transition temperature (Tr−t) were found to be in the range of 173–212°C and 114–155°C, respectively, indicating that the Tr-t was increased with adding PIN component. In the MPB region, the highest Tr-t = 155°C was found in 0.32PIN–0.38PMN–0.30PT ceramic, that greatly expanded temperature usage range.
