Abstract

All contributions to the total conductivity, electrolyte-electrode interfaces, grain boundaries, ion-hopping, and optical phonons, were determined on the 8 mol% yttria-stabilized zirconia (8YSZ) and 8 mol% ytterbia-stabilized zirconia (8YbSZ) ceramics using the wideband conductivity spectroscopy. Complex conductivity spectra from 10-1 Hz to 1014 Hz were successfully obtained. The higher total conductivity of the 8YbSZ ceramics compared to the 8YSZ in wideband frequencies was mainly attributed to difference in the DC conductivity due to universal dielectric response (UDR), σdc; σdc (8YbSZ) > σdc (8YSZ). Other parameters in the UDR and the optical phonon parameters did not greatly influence on the difference in their intrinsic conductivities.
