| Abstract: | Homogeneous,spherical and well distributed ZrO2-based powders were prepared by using a combined process which called co-precipitation and inorganic sol-gel.The ceramic electrolytes materials were obtained by compaction and pressureless sintering.Near full density was realized at 1 450 ℃.The results shown that the materials are full-cubic stabilized ZrO2 by using XRD and microstructure analysis.The ionic conductivity of 8YbSZ is higher than other ZrO2-based electrolytes materials when sintered in temperature range of 1 450-1 550 ℃ for 450-700 ℃ testing range.The value of conductivity already has reached 1.7×10-2 S·cm-1 when operated at 700 ℃.All above indicated that 8YbSZ is a better candidate for the electrolyte material of intermediate temperature solid oxide fuel cells. |
