Abstract

Abstract In this paper, novel (Er1-xYbx)3TaO7 oxides were synthesized via high-temperature sintering method at 1600 °C for 10–15 h. The lattice structure, microstructure, and thermophysical performances were studied. Results exhibit that the (Er1-xYbx)3TaO7 oxides have a single fluorite-type lattice and dense microstructure. Because of the phonon scattering caused by Yb2O3 addition, thermal conductivity of (Er1-xYbx)3TaO7 oxides decreases with increasing Yb2O3 content, which is lower than that of 7YSZ. Thermal expansion coefficient of (Er1-xYbx)3TaO7 oxides is elevated with increasing Yb2O3 fraction, which is close to that of 7YSZ. The prepared (Er1-xYbx)3TaO7 oxides also exhibit outstanding crystal-lattice steadiness up to 1200 °C.
