Description
Summary:oriented textured (Na0.5Bi0.5Ti)O3‐0.25SrTiO3 (NBT‐0.25ST) system was fabricated using 10 mol% plate‐like NBT template particles to enhance the electrical properties. Random and textured samples were prepared by a tape‐casting method. Lotgering factor for textured sample was calculated as 88%. Dielectric values of the samples were comparable, and this means texturing using NBT samples of this orientation did not change the dielectric constant. The maximum unipolar strain values of random and textured NBT‐0.25ST systems were found to be as ∼0.09% and ∼0.59%, respectively. This current study emphasizes the significant difference in maximum unipolar strain values between the random and textured versions of the NBT‐0.25ST system, indicating the superiority of the textured material in terms of responsiveness to the electric field. The FOM under high electric fields of textured and random NBT‐0.25ST was found to increase almost 45‐fold compared with random case.
