摘要:
采用固相反应法合成CeO2基电解质材料(1-x)(CeO2)0.92(Y2O3)0.06(Sm2O3)0.02+xCoO1.5(x=0、0.5%、1%和2%),并在不同温度下烧成。结果表明,添加Co的试样经1 500 ℃ 烧成之后合成了单一的立方萤石结构相,Co可以有效促进试样的烧结,降低烧结温度约100 ℃; 其中Co的添加量为0.5%时,试样表现出最高的离子电导率和最低的活化能。同时发现Co的添加对试样的热膨胀系数影响不大。
Abstract:
The ceria-based solid electrolyte materials(1-x)(CeO2)0.92(Y2O3)0.06(Sm2O3)0.02+ xCoO1.5(x=0, 0.5%, 1% and 2%)were prepared by solid state reaction method and sintered at different temperatures. The results showed that the Co doped samples all exhibited a single cubic fluorite phase after sintered at 1 500 ℃, and Co could effectively promote the sintering process and decrease the sintering temperature by 100 ℃. The maximum conductivity and the minimum activation energy were achieved with 0.5% Co addition. Meanwhile, the effects of Co addition on the thermal expansion were insignificant.
