Abstract

Texturing is an innovative method for fabricating high-performance piezoelectric ceramics. However, the optimal conditions for successful texturing must be evaluated to obtain high performance. Herein, the texturing behaviour of Pb(Mg1/3Nb2/3)O3�PbZrO3�PbTiO3 (PMN�PZ�PT) piezoelectric ceramics using plate-like BaTiO3 crystals as a template was found to be strongly dependent on the chemical composition of the matrix. Given that the solubility of BaTiO3 in the matrix increased with the PZ content, an excessive amount (>20 mol) of the BaTiO3 template was necessary for texturing a 0.2PMN�0.38PZ�0.42PT, while 3 mol of the BaTiO3 template could texture a 0.4PMN�0.22PZ�0.38PT. Owing to well-aligned textured grains and the complete consumption of randomly oriented matrix particles, a textured 0.4PMN�0.22PZ�0.38PT sample prepared by tape-casting under optimised conditions yielded a Lotgering factor of 97 and an induced strain of 0.2 with an electric field of 2 kV/mm. © 2021 Elsevier Ltd
