| 中文摘要 | The Al2O3–Ni–YSZ (Y2O3 stabilised ZrO2) anode materials with 0–6 wt% Al2O3 were prepared by tape casting method after being ball-milled for 48 h. The influence of Al2O3 content on flexural strength, electrical conductivity, open porosity, relative density and thermal expansion coefficient (TEC) of Al2O3–Ni–YSZ anode was investigated. The introduction of Al2O3 significantly enhances the flexural strength of Al2O3–Ni–YSZ anode. The flexural strengths of 430 and 299 MPa are achieved for the specimen containing 0.25 wt% Al2O3 before and after reduction, respectively, while the flexural strengths are 201 and 237 MPa for the Ni–YSZ samples. The density decreases with increasing Al2O3 content and the open porosity increases correspondingly, after being sintered at 1350 °C for 4 h. The electrical conductivity at ambient temperature does not fall off when Al2O3 content is less than 1 wt%, but decreases rapidly when the content is above 3 wt% due to the formation of NiAl2O4. A maximum electrical conductivity of 1418 S cm–1 is obtained in the sample containing 0.5 wt% Al2O3. The TEC of the samples decreases with the introduction of Al2O3 in the temperature range of 20–850 °C. |
