0.95(Na0.95-xKxLi0.05)(Nb0.90Sb0.05Ta0.05)O3-0.05KNbO3 lead-free piezoelectric ceramics were prepared by the conventional solid-state sintering method, the effects of K/Na ratio on the structure and electrical properties of the ceramics were studied in detail. The results show that the addition of the pre-calcined KNbO3 powder as sintering aid is very effective to improve the density and sinterability, and the ceramics could be well sintered at reduced temperature of 1060 °C as compared with the relatively higher sintering temperature of Li, Sb, Ta modified KNN ceramics reported in the literature at 1100-1220 °C. The ceramics with x=0.44 possess the optimal properties: d33=231 pC/N, kp= 47 %, Pr= 22 μC/cm2, and Ec= 11.4 kV/cm.
