Abstract

The total electrical conductivities were studied for the solid solutions in the pseudo-binary system CeO₂La₆WO₁₂. Maximum conductivities were observed at about 90 mol.% CeO₂, 1.1 ohm^-1 cm^-1 at 1500°C and 4.4 × 10^-3 ohm^-1 at 600°C. A minimum point was observed in conductivity isotherms at about 10 mol.% CeO₂. A pyrochlore like stoichiometric compound La₂ (LaCe_{1 2} W 1 2)O₇ was assumed. The crystal structure of La₆WO₁₂ is discussed. Ionic conductions were observed at low temperatures.
