Abstract

This letter provides a comparative description of the properties of textured and randomly oriented poly-crystalline lead-free piezoelectric 0.93(Na 0.5Bi 0.5TiO 3)-0.07BaTiO 3 (NBT-BT) ceramics. A high longitudinal piezoelectric constant of (d 33) ∼ 322 pC/N was obtained in (001) PC textured NBT-7BT ceramics, which is almost ∼2× times the d 33 coefficient reported for randomly oriented ceramics of the same composition. In situ neutron diffraction experiments revealed that characteristically different structural responses are induced in textured and randomly oriented NBT-BT ceramics upon application of electric fields (E), which are likely related to the varying coherence lengths of polar nanoregions and internal stresses induced by domain switching. © 2012 American Institute of Physics.
