摘要：

The high-entropy ceramic materials (Zr0.25Ce0.25Hf0.25Y0.25)O-1.875 (H-0) and (ZrZr0.2Ce0.2Hf0.2Y0.2RE0.2)O-1.8 (H -RE) (RE = La, Nd and Sm) with fluorite structure and homogeneous element distribution were prepared. With fluorite structure, fine grain size and high density, the H-0 and H-RE ceramics displayed low thermal conduc-tivity, suitable thermal expansion coefficient, high hardness and fracture toughness. The effect of La, Nd and Sm on the mechanical, heat conductivity and heat expansion properties of high entropy ceramics were discussed. The single-phase high-entropy ceramic materials in this work are very suitable for application as thermal barrier materials.
