摘要：

Methods of suppressing decreased conductivity in 8 mol% Y2O3-stabilized-92 mol% ZrO2 (8YSZ) with aging were investigated. Different amounts of Sc2O(3) were doped into 8YSZ. wThe electrochemical properties of Sc2O3-doped 8YSZ were measured, and the microstructural and local structural changes were characterized. The present results indicate that an appropriate amount of Sc2O3 doping, 3 or 4 mol%, effectively suppresses decreased conductivity with aging in 8YSZ.
