Abstract
Nanocrystalline powders of Y2Ru2O7 and Y2-xPrxRu2O7 were
prepared by a co-precipitation method. Pr was chosen as the Asite
dopant in order to increase the electrical conductivity of
Y2Ru2O7. Phase and morphology were studied by XRD and
FE-SEM, which showed both systems exhibit a particle size of
about 100 nm, and the doped powders were single pyrochlore
phase. The electrical conductivity of a dense bar of Y2-
xPrxRu2O7 was measured at several temperatures by d.c. 4-
probe method, while the electrochemical properties of Y2-
xPrxRu2O7 pyrochlores were tested in contact to ESB
electrolytes, using Electrochemical Impedance Spectroscopy
(EIS) in air. The Y2-xPrxRu2O7 on ESB electrolyte solid-state
cells presents a significant decrease of electrodes impedance.
