摘　　要：ZrO2陶瓷器件在700℃下退火处理1000h,研究了ZrO2基固体电解质的老化性能。结果表明:在700℃退火处理1000h后,8YSZ、8YbSZ和4Yb-8YSZ的电导率分别下降39%、49%和10%。比较8YSZ、4Yb-8YSZ和8YbSZ三种材料表明,在8YSZ二元系统中掺杂Yb2O3可改善ZrO2固体电解质材料的老化性能。ZrO2 ceramic was annealed at 700℃ for 1000 hours to investigate the aging behaviors of the zirconia-based solid electrolytes. The results showed that after annealed at 700℃ for 1000 hours, the decreases of the electric conductivities of 8YSZ, 8YbSZ and 4Yb-8YSZ were 39%, 49% and 10%, respectively. Compared with 8YSZ, 8YbSZ and 4YbSZ, Yb203 added into the ZrO2-Y2O3 binary system can improve the aging behaviors of the solid zirconia electrolytes.
