摘要: Dense 〈001〉-oriented (KxNa1 − x)0.946Li0.054NbO3 (KxNLN) ceramics with high texture quality (Lotgering factor F001 > 80%) and excellent piezoelectric properties were produced by templated grain growth using plate-like NaNbO3 particles as templates. Compared randomly oriented KxNLN ceramics, textured samples show greatly enhanced properties. The room-temperature strain hysteresis S, the coefficient d33 reach up to 0.15–0.21%, 333–471 pm/V, 231–254 pC/N, respectively, which are all about 1.6–1.8 times larger than those of nontextured same composition. temperature-dependent characteristic is shown in both around polymorphic phase transition (PPT) temperature, confirming that this behavior determined PPT unaffected texturing. Moreover, good resistance thermal depoling was obtained indicating system a very promising material for high-temperature applications.
