Abstract

This study reports the dielectric and piezoelectric properties of 0.4Pb(Mg_1/3Nb_2/3)O₃-0.25PbZrO ₃-0.35PbTiO₃ (PMN-PZT), 2 mol% MnO₂-doped 0.4Pb(Mg_1/3Nb_2/3)O₃-0.25PbZrO ₃-0.35PbTiO₃ (MnO₂+PMN-PZT), and 0.06Pb(Mn _1/3Nb_2/3)O₃-0.34Pb(Mg_1/3Nb _2/3)O₃-0.25PbZrO₃-0.35PbTiO₃ (PMnN+PMN-PZT) ceramics. The results show that MnO₂ modification results in the formation of MgO secondary phase which promotes grain growth and reduces the electromechanical properties. We conclusively demonstrate that Mn²⁺ acts as pervoskite stabilizer in Pb-based (1:2) relaxors and leads to the formation of divalent oxide secondary phase. Modification with PMnN avoids the formation of MgO and provides combinatory doping effect with smaller grain sizes.
