Enhanced Piezoelectric Properties From the Electric Field-Induced Ferroelectric Transition at the MPB of BiGaO₃-Substitued NaBiTiO₃-BaTiO₃(NBT-BT).

A ternary solid solution of lead-free NaBiTiO-BaTiO and BiGaO (NBT-BT-BG) was prepared using conventional, solid-state synthesis. Compositions were prepared near the morphotropic phase boundary (MPB) of ( 1- x )NBT- x BT, located near x = 0.04 -0.
