Abstract

Pyrochlore structure oxide (La_0.5Sm_0.5) ₂(Zr_0.9Ce_0.1)₂O₇ was prepared by mixing the appropriate amounts of ZrO₂, La ₂O₃, Sm₂O₃ and CeO₂, followed by reacting at 1600°C for 10 h. It was shown that the thermal conductivity was much lower than that of 8YSZ, which was mainly ascribed to the oxygen vacancies and lattice strain in lattice of (La_0.5Sm _0.5)₂(Zr_0.9Ce_0.1)₂O ₇.
