초록

This paper is the study for electrical characteristic of PZT ceramics with Sb$_2$O$_3$, CoO additive. Effect of Sb$_2$O$_3$, CoO additive ranged from 0.0 wt% to 1.2wt% on the electrical characteristic of the PZT ceramics have been investigated. In the case of Sb$_2$O$_3$ 0.6wt%, the maximum vague of mechanical quality factor(Qm) was obtained 124.11 at l15$0^{\circ}C$. And, additive CoO 1.2wt% was obtained 184.12 at l15$0^{\circ}C$. The electromechanical coupling factor(kp) was increased by increasing the amount of Sb$_2$O$_3$, CoO additive. The maximum value of electromechanical coupling factor(kp) was obtained 58.35 with Sb$_2$O$_3$1.2wt% additive at l15$0^{\circ}C$. Dopped with additive CoO 0.9wt%, electromechanical coupling factor(kp) was obtained 47.84 at 115$0^{\circ}C$.
