Abstract: The (La0.2Sm0.2Gd0.2Y0.2Yb0.2)3Nb0.5Ta0.5O7 was designed and synthesized adopting chemical method and high-temperature calcining technique. Its phase structure, micromorphology, element content and type, and thermophysical and mechanical performances were studied. The final conclusions indicate that the achieved high-entropy compound has a sole pyrochlore lattice, dense microstructure and mean distribution of element. Because of the aggravated phonon scattering caused by the substitutional cations, oxygen vacancies and lattice distortion, its room and high-temperature thermal conductivities were less than that of Y2O3 stabilized zirconia (YSZ). The high-entropy compound also exhibits a great thermal expansion coefficient and phase steadiness until 1200 °C, its elastic modulus was higher than that of YSZ, while its fracture toughness and microhardness were smaller than corresponding values of YSZ.
