| 中文摘要 | Six samples of mixed Y2O3/CaO doped ZrO2 electrolytes, with the same nominal chemical composition of (ZrO2)(0.90)-(Y2O3)(0.04)- (CaO)(0.06), were sintered at 1600 degreesC for 2, 4, 6, 8, 10 and 15 h, respectively, to make the grain size differ from sample to sample. The grain-boundary conductivity of each sample was measured using complex impedance method in the temperature range from 673 to 1073 K and experimental results were analyzed according to the Arrhenius equation. It was found that variation in grain size can produce large change in the activation energy for grain-boundary conduction, E-gb, and there exists a particular grain size at which E-gb reaches a maximum. Such an experimental phenomenon was then analyzed based on two existing models., the constriction resistance model and the brick layer model, and a possible explanation was proposed.
