Abstract

New morphotropic phase boundary (MPB) piezoelectrics with ferroelectric phase transitions (Tc) exceeding that of PbZrO3-PbTiO3 (PZT) were investigated. Based on a perovskite tolerance factor - Tc relationship, new high Tc 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 Tc of ∼ 450°C was determined with higher Tcs projected with lower tolerance factor systems.
