Abstract

Abstract: In this paper, for developing the piezoelectric ceramics suitable for ultrasonic surgical instruments application, (0.10- x ) Pb (Mn1/3 Nb2/3 )O3 -x Pb(Ni1/3 Nb2/3 )O3 -0.91Pb(Zr1/2 Ti1/2 )O3 (x=0. 0.015, 0.03, 0.045, 0.06, 0.075) ceramics were manufactured and then their physical characteristics were systematically analyzed. When Pb(Ni1/3 Nb2/3 )O3 and sintered temperature were is 0 mol%, 940°C, respectively, the excellent electrical properties (d33=236 pC/N, εr=731.9, kp=0.5839, Qm=1982) were obtained for ultrasonic surgical instruments and actuators.
