Abstract
- Methods of suppressing decreased conductivity in 8 mol% Y[sub 2]O[sub 3]-stabilized-92 mol% ZrO[sub 2] (8YSZ) with aging were investigated. Different amounts of Sc[sub 2]O[sub 3] were doped into 8YSZ. The electrochemical properties of Sc[sub 2]O[sub 3]-doped 8YSZ were measured, and the microstructural and local structural changes were characterized. The present results indicate that an appropriate amount of Sc[sub 2]O[sub 3] doping, 3 or 4 mol%, effectively suppresses decreased conductivity with aging in 8YSZ. [ABSTRACT FROM AUTHOR]
