Abstract
Piezoelectric devices such as piezoelectric speaker, motor, and actuator have been actively researched. Accordingly, for developing the ceramics capable of being sintered at low temperature for piezoelectric devices, 0.97(Na0.52K0.443Li0.037)(Nb0.923Sb0.04 Ta0.037)O3 − 0.03(Bi0.5Na0.5)0.9(Sr)0.1ZrO3 ceramics were manufactured according to x (=sintering time) and their piezoelectric and dielectric properties were systematically investigated. At the x = 9 h, the best piezoelectric properties of d33 = 244.33pC/N εr = 1475, and kp = 0.441 were appeared, respectively, for piezoelectric devices.
