In this manuscript, the Ca3Ln3Ti7Ta2O26.5 (Ln = Y and Yb) oxides were prepared by employing a high-temperature solid-phase reaction method at 1773 K for 10 h. The phase compositions and thermal-physical performances were studied. The results show that the synthesized oxides are of a single pyrochlore-type lattice, the thermal conductivity of Ca3Y3Ti7Ta2O26.5 is larger than that of Ca3Yb3Ti7Ta2O26.5, and the coefficient of thermal expansion of Ca3Yb3Ti7Ta2O26.5 is higher than that of Ca3Y3Ti7Ta2O26.5. The thermal-physical properties match well with the requirements for ...
