Abstract: The microstructure and piezoelectric properties of Pb0.98Sr0.02(Mn1/3 Sb2/3)x-(Zr0.5Ti0.5)1-xO3 ceramics were investigated systematically as a function of NiO-doping contents. Results show that, phases shift from tetragonal to rhombohedral phase with the increase of doping amounts, the solubility of NiO in PMS-PZ-PT ceramics is very small, and the composition with doping amount of 0.02wt% has superior piezoelectric properties. The modified compositions are practically suitable for ultrasonic motor (USM) applications.

Key words: PMS-PZ-PT, NiO doping, piezoelectric properties, USM
