摘要

Mn-doped 0.49 Pb(Ni_1/3Nb_2/3)O₃-0.51 Pb(Hf_0.3Ti_0.7)O₃ (abbreviated PNN-PHT) ceramics were prepared by solid-phase reaction method. The influence of defect dipoles on various properties was systematically studied. Results showed that Mn doping significantly improved mechanical quality factor Q_m of PNN-PHT ceramics and greatly reduced dielectric loss, while Curie temperature T_c was also slightly increased. After 10⁵ electric field cycles, Mn doped PNN-PHT ceramic showed excellent fatigue property. Based on ferroelectric and dielectric properties of samples, the reason for defect dipole and internal mechanism of its influence on piezoelectric properties were elucidated. Finally, novel ceramic 0.75 mol% Mn-doped PNN-PHT with excellent performance was obtained (d₃₃~750 pC/N, k_p~0.55, Q_m~384 and tanδ~0.59%). Therefore, results of this work suggest that these ceramics may be potential candidates for piezoelectric actuators and high-power devices.
