Piezoelectric Properties of 0.99(Na zK1- z)Nb0.955O3-0.045LiSbO3-0.01CaTiO3 Lead-free Ceramics
A0.99(Na xK1- x)Nb0.955O3-0.045LiSbO3- 0.01CaTiO3 (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 d33=266 pC/N, planar electromechanical coupling factors kp=48.7 %. These results show that the NKNLS-CT ceramics may be regarded as the promising lead-free piezoelectric materials.
