Abstract

New morphotropic phase boundary (MPB) piezoelectrics with ferroelectric phase transitions (T_c) exceeding that of PbZrO₃-PbTiO₃ (PZT) were investigated. Based on a perovskite tolerance factor - T_c relationship, new high T_c MPB systems were projected in Bi(Me)O₃-PbTiO₃ systems, where Me is a relatively large B⁺³-site cation. For the (1-x)BiScO₃-(x)PbTiO₃ solid solution, a MPB was found at x-0.64 separating the rhombohedral and tetragonal phases, with correspondingly enhanced dielectric and piezoelectric properties. A transition temperature T_c of ∼ 450°C was determined with higher T_cs projected with lower tolerance factor systems.
