The superior thermo-physical performance above enables (La 0.2Nd 0.2Sm 0.2Eu 0.2Gd 0.2) 2Ce 2O 7 a promising TBC material. Benefiting from the solid solution strengthening effect, it shows a higher hardness of 8.72 GPa than the corresponding single component compounds. Through high-temperature in-situ X-ray diffraction (XRD) measurement, this material shows excellent phase stability up to 1400 ☌. K −1 at 1400 ☌, which can be explained by the existence of high concentration oxygen vacancies and highly disordered arrangement of multicomponent cations in the unique high-entropy configuration.Besides, it presents prominent thermal insulation behavior with a low intrinsic thermal conductivity of 0.92 W Notably, it exhibits a much higher TEC of approximately 12.0 × 10 −6 K −1 compared with those of other high-entropy oxides reported in the field of TBCs. The as-prepared multicomponent material is formed in a simple disordered fluorite structure due to the high-entropy stabilization effect. In order to improve the poor thermal expansion property and further reduce the thermal conductivity, high-entropy (La 0.2Nd 0.2Sm 0.2Eu 0.2Gd 0.2) 2Ce 2O 7 is designed and synthesized in this work. However, the relatively low thermal expansion coefficient (TEC) of those materials severely restricts their practical application. High-entropy oxides (HEOs) are widely researched as potential materials for thermal barrier coatings (TBCs). ![]()
