| 中文摘要 | The powders of 89 mol% ZrO2-11 mol% Sc2O3 (11ScSZ) doped with various Mn2O3 contents were prepared by a co-precipitation method combined with a SCFD (supercritical fluid drying) route. Inhibition of the cubic-rhombohedral phase transformation in both oxidation and reduction atmospheres is achieved for I I ScSZ by the addition of 2.0 mol% Mn2O3. The Mn2O3 addition can lower the sintering temperature of I I ScSZ ceramics, and the 11 ScSZ-2Mn(2)O(3) compact can be sintered to nearly full density at 850 degrees C. 11 ScSZ-2Mn(2)O(3) ceramic with the cubic structure sintered at 900 degrees C possesses the conductivity of similar to 0.10 S cm(-1) at 800 degrees C, which is very promising for intermediate temperature solid oxide fuel cell (SOFC) applications.
