Abstract

MnO₂ was added to 0.75Pb(Zr_0.47Ti_0.53) O₃-0.25Pb(Zn_1/3Nb_2/3)O₃ (0.75PZT-0.25PZN) ceramics in order to make a high-power piezoelectric material. The Mn⁴⁺ ion produced a defect dipole consisting of an Mn ⁴⁺ ion and an oxygen vacancy that transformed the 0.75PZT-0.25PZN ceramics into hard materials. The Q_m value significantly increased with the addition of MnO₂ and reached a value of 1680 for the 1.5 mol% MnO₂-added 0.75PZT-0.25PZN ceramic. Moreover, this specimen exhibited a high k_p of 0.53 with a ε₃ ^T/ε₀ of 1518. Additionally, the 1.5 mol% MnO ₂-added 0.75PZT-0.25PZN ceramics sintered at 900°C for 4 h also exhibited high piezoelectric properties of Q_m=1115, k _p=0.50, and ε₃^T/ε₀=1537.
