| 中文摘要 | a series of solid electrolytes ce1-xgdxo2-x/2(x=0 similar to0.6) was prepared by sol-gel method. the structure, thermal expansion coefficient and electrical properties of the solid solutions were systematically studied. xrd data showed that a complete cubic fluorite structure was formed at 160 degreesc. the purity of the product prepared by the sol-gel method is higher, the grain size is uniformly smaller. they were easily sintered into highly dense ceramic pellets at 1 300 degreesc. the sintering temperature was significantly lower than that by traditionally high temperature solid phase reaction method. the thermal expansion coefficient of ce0.8gd0.2o1.9, determined from high- temperature xrd data, is 8. 125 x 10(-6) k-1. impedance spectra analyses showed that the grain-boundary resistance of the solid electrolyte prepared by sol-gel method was reduced or even eliminated. the conductivity of ce0.8gd0.2o1.9 is 5.26 x 10(-3) s/cm at 600 degreesc. the activation energy (e-a) is 0.82 ev. |
