摘要(1 − x)(0.948K0.5Na0.5NbO3 − 0.052LiSbO3) − xBi2O3(x = 0.001 ~ 0.004) (abbreviated as KNN − 5.2LS − xBi) lead-free piezoelectric ceramics were prepared using conventional solid sintering method and the effect of bismuth oxide (Bi2O3)-doping on phase structure, microstructure and electric properties were investigated. It was found that Bi2O3-doping induces a phase transition from the tetragonal phases to a pseudocubic phase with a normal-relaxor ferroelectric transformation, and acts as grain growth inhibitor, which significantly decreases the grain size of the ceramics. The KNN − 5.2LS ceramic with 0.2 mol. % Bi2O3exhibited the optimum electrical properties (d33 = 229 pC/N, kp = 31.08 %), together with a low TO–Tof 77 °C. In addition, the highest TC(∼355 °C), the highest Smax(∼0.20 %) and d33* (∼392 pm/V) values can be attained in the ceramics with x = 0.001, which is superior to those of the previously reported KNN-based ceramics. These results show that the KNN − 5.2LS − xBi ceramic is one of the most promising candidates for replacing PZT-based ceramics. © 2016, Springer Science+Business Media New York.
