Ceria‐doped scandia‐stabilized zirconia (10Sc 2 O 3 ·1CeO 2 ·89ZrO 2 ) as electrolyte for SOFC s: Sintering and ionic conductivity of thin, flat sheets
Source abstract
Abstract
Abstract In this study, thin, flat sheets, about 90 μm thick, were prepared from ceria‐doped scandia‐stabilized zirconia with molecular formula 10Sc 2 O 3 ·1CeO 2 ·89 ZrO 2 (10Sc1Ce SZ ) by tape casting and subsequent sintering at different thermal cycles. A sintering thermal cycle was selected that yielded defect‐free flat sheets, with practically negligible porosity (between 0.35% and 0.10%) and average grain diameters ranging from 1.32 to 6.30 μm. Ionic conductivity at 600°C was as high as 21 mS /cm. Ionic conductivity increased with average grain diameters up to 2.7 μm. At higher average grain diameters, conductivity remained practically constant.
