Physical Characteristics of (1 − x)[(Na,K)(Nb,Sb)O3]–(Bi,Na)ZrO3–xBaZrO3 Ceramics for Piezoelectric Actuator

Abstract

In this paper, for developing the excellent composition ceramics for piezoelectric actuator application, the (1 − x)[(Na,K)(Nb,Sb)O3]–(Bi,Na)ZrO3–xBaZrO3 ceramics were fabricated according to BaZrO3 substitution and the their physical characteristics were analyzed. An average grain size of the ceramics was slowly reduced according to BaZrO3 addition. When x = 0.015, an excellent physical properties of density = 4.44 g/cm3, Qm = 95.47, kp = 0.403, εr = 2041, and d33 = 271pC/N were observed. These results show that the ceramics with x = 0.015 is an attractive candidate for lead-free piezoelectric actuator.
