| 520 | |a Abstract The structure, thermal expansion coefficients and ionic/electronic conductivity of ($ Ce_{1-x} %$ Sm_{x} $)1-y(Tb/Pr)y$ O_{2-x/2)+δ} $ (x=0-0.30; y=0-0.10) and $ Ce_{1-x} %$ Ca_{x} %$ O_{2-x} $ (x= 0-0.17) solid electrolytes prepared hydrothermally were investigated. The uniformly small particle size (7-68 nm) of the hydrothermally prepared materials allows sintering of the samples into highly dense ceramic pellets at 1400°C, a significantly lower temperature, compared to that at 1600–1650°C required for samples prepared by solid state techniques. The maximum ionic conductivity in $ Ce_{1-x} $(Sm/Ca)x$ O_{2-δ} $ was found at x=0.17 for the Sm ($ σ_{600°c} $ = 5.7×$ 10^{-3} $ S/cm). In ($ Ceo_{0.83} %$ Sm_{0.17} $)1-y(Tb/Pr)y$ O_{1.915+δ} $ the maximum conductivity was found at y= 0.17 for the Pr and Tb substituted ceria ($ σ_{600°c} $=7.$ 6x10^{-3} $S/cm, $ E_{a} $= 0.55 eV and $ σ_{600°c} $ = $ 10^{-2} $ S/cm, $ E_{a} $= 0.72 eV respectively) with electronic contribution to total conductivity around 20–30 %. When the Tb or Pr substitution in $ Ce_{0.83} %$ Sm_{0.17} %$ O_{1.915} $ is reduced, the conductivity becomes more ionic, and is purely ionic at 2 %. However the conductivity at this lower level doping is not significantly lower. | ||

Hydrothermal Synthesis and Properties of Ceria Solid Electrolytes |
| abstract |
Abstract The structure, thermal expansion coefficients and ionic/electronic conductivity of ($ Ce_{1-x} %$ Sm_{x} $)1-y(Tb/Pr)y$ O_{2-x/2)+δ} $ (x=0-0.30; y=0-0.10) and $ Ce_{1-x} %$ Ca_{x} %$ O_{2-x} $ (x= 0-0.17) solid electrolytes prepared hydrothermally were investigated. The uniformly small particle size (7-68 nm) of the hydrothermally prepared materials allows sintering of the samples into highly dense ceramic pellets at 1400°C, a significantly lower temperature, compared to that at 1600–1650°C required for samples prepared by solid state techniques. The maximum ionic conductivity in $ Ce_{1-x} $(Sm/Ca)x$ O_{2-δ} $ was found at x=0.17 for the Sm ($ σ_{600°c} $ = 5.7×$ 10^{-3} $ S/cm). In ($ Ceo_{0.83} %$ Sm_{0.17} $)1-y(Tb/Pr)y$ O_{1.915+δ} $ the maximum conductivity was found at y= 0.17 for the Pr and Tb substituted ceria ($ σ_{600°c} $=7.$ 6x10^{-3} $S/cm, $ E_{a} $= 0.55 eV and $ σ_{600°c} $ = $ 10^{-2} $ S/cm, $ E_{a} $= 0.72 eV respectively) with electronic contribution to total conductivity around 20–30 %. When the Tb or Pr substitution in $ Ce_{0.83} %$ Sm_{0.17} %$ O_{1.915} $ is reduced, the conductivity becomes more ionic, and is purely ionic at 2 %. However the conductivity at this lower level doping is not significantly lower. |
