Abstract

Textured (1 - x - y)Bi_0.5Na_0.5TiO₃-(x) BaTiO₃-(y)K_0.5Na_0.5NbO₃ ceramics have been produced by tape casting with pure-phase Bi_0.5Na _0.5TiO₃ templates. Rietveld texture refinement was used to analyze the crystallographic preferred orientation of the fired ceramics. The effect of poling field on d₃₃ was investigated for applied fields between 0-8 MV m^-1 for pure Bi_0.5Na_0.5TiO ₃ and 0-5 MV m^-1 for Bi_0.5Na _0.5TiO₃ alloys, and compared against randomly oriented samples. Texturing enhanced the piezoelectric response of all measured compositions with Bi_0.5Na_0.5TiO₃-(5)BaTiO ₃ reaching a maximum d₃₃ of 245 pC N^-1.
