dc.description.abstractSolid electrolytes based on rare earth-doped cerium dioxide are of considerable interest for potential application in intermediate- temperature solid oxide fuel cells, IT-SOFC. Nevertheless, some constraints related to their sintering behavior along with improvement of the ionic conductivity are still object of investigation. In this work, dysprosium ion was chosen as a second additive/dopant, aiming to obtain a ceramic solid electrolyte with optimized ionic conductivity. Compounds of Sm0.2-xDyxCe0.8O1.9 with 0 % x % 0.2 were prepared by solid-state reaction, and the influence of the additive content on densification and ionic conductivity was analyzed by density, X-ray diffraction and impedance spectroscopy measurements. All compositions were found to exhibit cubic fluorite-type structure. The sintered solid electrolytes achieved densities higher than 92% of the theoretical value after sintering at 1500°C/3 h, and higher ionic conductivity than the Sm0.2Ce0.8O1.9 parent electrolyte.pt_BR
