Abstract

The effects of acceptor doping with manganese as either MnO₂ or MnNb₂O₆ (MnN) with CuO on the dielectric, ferroelectric, and piezoelectric properties of PIN-PMN-PT ceramics were investigated. The 2% MnNb₂O₆-doped PIN-PMN-PT (6Pb(Mn_1/3Nb_2/3)O₃-25Pb(In_1/2Nb_1/2)O₃-34Pb(Mg_1/3Nb_2/3)O₃-35PbTiO₃) ceramics possessed hard properties such as high coercive field (E_C) of 11.7 kV/cm, low dielectric loss (tan δ) of 0.7%, and high electromechanical quality factor (Q_M) of 1011. These properties were diminished in MnO₂-doped ceramics because of lower oxygen vacancy defect concentration, and exaggerated grain growth resulted in >20 µm grain size. Co-doping with 2 mol% MnNb₂O₆ and 0.5 mol% CuO retained hardened properties such as high E_C of 9.6 kV/cm, low tan δ of 0.6%, and high Q_M of 1029. MnNb₂O₆-doped and MnNb₂O₆ + Cu co-doped ceramics display excellent figures of merit for resonance and off-resonance applications as well as high energy conversion efficiencies which make them promising candidates for high-power transducer elements.
