This work provides a comparative study of the dielectric and piezoelectric properties of randomly oriented and textured 0.88Na 0.5 Bi 0.5 TiO 3 -0.08K 0.5 Bi 0.5 TiO 3 -0.04BaTiO 3 (88NBT) ceramics. Textured ceramics were fabricated by template grain growth (TGG) method using NaNbO 3 (NN) for templates. For textured ceramics with 4 wt% NN templates, a Lotgering factor of 96% and piezoelectric coefficient d 33 of 185 pC/N were obtained. Compared to the randomly oriented ceramics, textured ceramics show lower strain hysteresis (H = 7.6%), higher unipolar strain of 0 ...
