Kurzbeschreibung (Abstract)
Textured (1−x−y)Bi1/2Na1/2TiO3–xBaTiO3–yK0.5Na0.5NbO3 (BNT–100xBT–100yKNN) ceramics with a {001} pseudocubic (pc) orientation were fabricated by templated grain growth using Bi1/2Na1/2TiO3 templates. Temperature-dependent electromechanical results demonstrate that the strain response of templated BNT–xBT–yKNN ceramics is stable from room temperature (RT) to 125°C. The temperature-dependent strain and polarization response are compared to randomly oriented ceramics, for BNT–100xBT–2KNN (0.05 ≤ x ≤ 0.07). Textured BNT–7BT–2KNN reached a maximum 0.47% strain response at 5 kV/mm, an almost 50% increase compared to randomly oriented BNT–7BT–2KNN. Over the temperature range RT–125°C, the strain response of templated BNT–6BT–2KNN degraded from 0.38% to 0.22% (−42.1%) compared to 0.37% to 0.18% (−51.4%) for randomly oriented ceramics. The temperature-dependent strain response suggests that templated BNT–100xBT–100yKNN ceramics are well suited for elevated temperature applications.
