In this paper, for developing the excellent composition ceramics for piezoelectric actuator application, the (1 − x)[(Na,K)(Nb,Sb)O 3 ]–(Bi,Na)ZrO 3 –xBaZrO 3 ceramics were fabricated according to BaZrO 3 substitution and the their physical characteristics were analyzed. An average grain size of the ceramics was slowly reduced according to BaZrO 3 addition. When x = 0.015, an excellent physical properties of density = 4.44 g/cm 3 , Q m  = 95.47, k p  = 0.403, ε r  = 2041, and d 33  = 271pC/N were observed. These results show that the ceramics with x = 0.015 is an attractive candidate for lead-free piezoelectric actuator.
