Abstract

Electrochemical properties of Pb1-xLaxZrO3+x/2 with perovskite structure have been studied. The powdery Pb1-xLaxZrO3+x/2 has been prepared by solid-state reaction method. The X-ray diffraction analysis reveals that Pb1-xLaxZrO3+x/2 (x = 0.0-0.05) sintered at 900 ËšC was single phase structure. The electrical conductivity of the material has been investigated. By doping La at the lead site, the electrical conductivity of the Pb1-xLaxZrO3+x/2 system decreased. The undoped compound showed the highest electrical conductivity of ca. 10-3 S/cm. Electromotive Force (EMF) measurements of oxygen concentration cell confirm that the charge carrier of La doped PbZrO3 was the oxide ion.
