چکیده
|
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 ˚c 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.
