The solid solution of 0.94(Na0.5Bi0.5)TiO3-0.06BaTiO(3) NBBT94/06 is a promising material to replace Lead (Pb) based piezoelectric materials. The bulk NBBT 94/06 single crystal was successfully grown by the top-seeded solution growth (TSSG) method. Lead-free piezoelectric NBBT single crystals with a composition across the morphotropic phase boundary (MPB) have been grown by the TSSG method. NBBT 94/06 single crystal, encompassing the rhombohedral to largely monoclinic phase covering the MPB region was grown by the TSSG method. The crystal structure and its electrical properties were investigated. The Laue diffraction pattern confirms that the grown crystal is a single crystal. Rietveld refinement studies disclose the existence of a phase boundary between Monoclinic (Cc) and Rhombohedral (R3c) phases near the MPB. The depolarization temperature (T-d), piezoelectric coefficient (d(33)) and ferroelectric properties were enhanced at MPB. (C) 2020 Elsevier B.V. All rights reserved.
