Effects of Doping on Microstructure and Piezoelectric Properties ofPMS-PZ-PT Ceramics
Source abstract
Abstract
The microstructure and piezoelectric properties of Pbo.98Sro.o2(Mn1/3 Sb2/3)x-(Zr0.5Ti0.5)1-xO3 ceramics with different dopants of Nb2O5, NiO, Fe2O3 and doping amounts were Investigated. Results show that phases shift from tetragonal phase to rhombohedral phase with the increase of doping amounts. The solubility of B-site dopants in PMS-PZ-PT ceramics is very small. The compositions with small doping amount have optimized property values of d33, Kp and Qm. The Qm can be improved with small amount of acceptor dopants, but deceases all through with the increase of Nb-doping concentration. The modified compositions have superior piezoelectric properties, so they are practically suitable for the applications in ultrasonic motors.
