Abstract

A sample of 0.83Pb(Zr_0.5Ti_0.5)O₃-0.11Pb(Zn_1/3Nb_2/3)O₃-0.06Pb(Ni_1/3Nb_2/3)O₃ (PZNNT) to which MnO₂ was added, with a high mechanical quality factor (Q_m) and a good transduction coefficient (d₃₃×g₃₃), were systematically investigated. Based on the SEM analysis there existed two kinds of “secondary phases”, Rich Ti and Rich Zn phases, which arose due to the B-site substation of PZNNT-based ceramics by manganese ions. One phase was due to the Mn³⁺ replacing the Ti⁴⁺ to create oxygen vacancies and induce the hardening effect. Another phase was due to the Mn²⁺ replacing the Zn-site to stabilize the perovskite phase. When the addition of MnO₂ reached the solubility limit of 1.5 mol% in the PZNNT-based ceramics, the sample showed optimal electrical properties (Q_m=357, d₃₃×g₃₃=9859 × 10⁻¹⁵ m²/N, k_p=0.56), which suggested its potential application for piezoelectric energy harvesting in larger field excitation environments.
