The as-synthesized powders are completely converted to ceria with fluorite structure. The original morphology and the nanometric features are also preserved. Nearly perfect dense products were obtained after sintering at 1300 degrees C for 3 h, as by SEM and density measurements. Electrochemical measurements proved that they are all suitable as electrolytes for IT-SOFC. (C) 2017 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
