抜粋

In order to clarify the mixing effect of cation on the electrical conductivity and the hydration, the electrical conductivity of La 0.9Sr0.1(Yb1 - xMx)O 3 - δ (M = In, Y) has been determined by the four-probe AC technique in the temperature range of 673-1173 K. The proton concentration was estimated from the change in weight due to hydration by a thermogravimetric analysis. The conductivity and proton concentration increased with the increase in the In3 + content on the Yb-site. On the other hand, the electrical conductivity and protonic concentration of La0.9Sr 0.1(Yb1 - xYx)O3 - δ showed minimum values at x = 0.5.
