Abstract

In this study, in order to develop the low temperature sintering ceramics for ultrasonic vibrator, Pb(Sb $\_$ $\frac{1}{2}$ /Nb $\_$ $\frac{1}{2}$ /) O $_3$ -Pb(Ni $\_$ 1/3/Nb $\_$ 2/3/)O $_3$ -Pb(Zr $\_$ 0.48/Ti $\_$ 0.52/)O $_3$ ceramics were manufactured as a function of the amount of CuO addition, and their dielectric and piezoelectric characteristics were investigated. With increasing CuO addition, the grain size and density increased up to 0.3 wt% CuO addition. Taking into consideration electromechanical coupling factor(k $\_$ p/) of 0.53, mechanical quality factor(Q $\_$ m/) of 423, dielectric constant( $\varepsilon$ $\_$ r/) of 1,759 and piezoelectric constant(d $\_$ 33/) of 362pC/N, it could be concluded that 0.5 wt% CuO added composition ceramic sintered at 920 $^{\circ}C$ was suitable for ultrasonic vibrator application.
