0.99[(Na x K 1-x )Nb 0.955 O 3 -0.045LiSbO 3 ]-0.01CaTiO 3 (NKNLS-CT) lead-free piezoelectric ceramics have been prepared by the conventional mixed oxide method. The effect of the K/Na ratio on the electrical properties of NKNLS-CT ceramics was investigated. When x = 0.52, the ceramics possess optimum properties: piezoelectric constant d 33 =266 pC/N, planar electromechanical coupling factors k p =48.7 %. These results show that the NKNLS-CT ceramics may be regarded as the promising lead-free piezoelectric materials.
