Effects of Sb or Ba Addition on the Piezoelectric Properties of PZT

Abstract:

Lead zirconate titanate (PZT) materials are wildly used in aviation, industry and our daily life. Actually, it becomes more and more important to improve its electrical properties. In this paper, the influences of antimony (Sb)-doping and barium (Ba)-doping and sintering temperature upon properties of PZT ceramics have been investigated. The relationships between the microstructure and electrical properties have been analyzed by means of XRD, SEM and impedance analyzer, etc.The XRD patterns indicate that all samples exhibit the tetragonal perovskite structure.This research also suggests that the best sintering temperature is 1190°C if the doping amount of Sb₂O₃ and BaCO₃ are 0.6wt% and 0.2wt% respectively. In this case, the samples possess perfect electrical properties: tanδ=0.02, k_p=66.3%, d₃₃=438pC/N, ε=1740.
