Abstract
In this study, in order to develop excellent lead free piezoelectric ceramics for piezoelectric actuators application, $Li_{0.04}(Na_{0.50}K_{0.50})_{0.96}[(Nb_{0.86}Ta_{0.10}Sb_{0.04})_{0.994}Co_{0.015}]O_3+0.0025SrO+0.15\;wt%K_2CO_3+x\;wt%Nb_2O_5$ (x = 0 - 0.5 wt%) (abbreviated as LNKNTSCS-xN) ceramics were fabricated by a conventional sintering technique. the phase structure, microstructure and electrical properties were investigated with a emphasis on the influence of the $Nb_2O_5$ content. High electrical properties of $d_{33}$=234 pC/N, kp=0.392, ${\varepsilon}_r$=1,395, ${\rho}=4.70g/cm^3$ were obtained from the specimen with x=0.4 wt%, which suggests that the composition ceramics is a promising lead-free piezoelectric material.
