Paper Title:
Effectively Doping of Rare Earth Additives in Sol Gel Derived PZT Ceramics
  Abstract

The PZT-based ceramics with a composition of Pb1.1-sRs (Zr0.53Ti0.47)O3.1+0.5s; s = 0.00 – 0.02, R= La, Nd, Sm were prepared by conventional mixed-oxide, and sol-gel methods, with optimal preparation conditions. The microstructural and electrical properties were examined as a function of the additive content and type then compared. Microstructural and compositional analyses of the PZT-based ceramics have been carried out using SEM and XRD. Dielectric properties of the samples were measured with an impedance analyzer. The ferroelectric properties of the PRZT samples were measured using the frequencies. It showed that the La additive improved both the dielectric and piezoelectric properties. Using sol gel method decreased saturation point of PZT. The PRZT with 0.5 mol% La be in optimum condition
