Dielectric and piezoelectric properties of manganese-modified PbHfO3-PbTiO3-Pb(Mg1/3Nb2/3)O3 ternary ceramics with morphotropic phase boundary compositions

Journal Article


Abstract


  • High piezoelectric and electromechanical properties were reported in the PbHfO3–PbTiO3–Pb(Mg1/3Nb2/3)O3 ternary system with morphotropic phase boundary (MPB) compositions. This work focuses on the effect of MnO2 addition on 0.8Pb(Hf0.443Ti0.557)O3–0.2PMN (0.8PHT–0.2PMN) ceramics. It was observed that the Mn acceptor modification induced a “hardening” effect in 0.8PHT–0.2PMN, with decreased piezoelectric coefficients d33 and dielectric loss tan δ and a significantly increased mechanical quality factor Qm. Moreover, the 0.2 wt% MnO2-doped 0.8PHT–0.2PMN ceramics exhibited good piezoelectric and electromechanical properties with d33, planar electromechanical coupling kp and Qm being on the order of 360 pC/N, 61% and 700, respectively, showing advantages compared to those of commercial hard PZT4 ceramics, which is attractive for high power applications.
