摘要：
As a new class of ceramic material system, high-entropy ceramics (HECs) have become a research hotspot due to their compositional and structural diversity. HECs have the characteristic of severe lattice distortion. The thermal conductivity of HECs can be significantly reduced by increasing phonon scattering. The mechanical properties of HECs are enhanced by the solid solution strengthening. In addition, the catalytic and electrical properties of HECs can be improved by uniform distribution of active sites for polymetallic cations, stable high configurational entropy and chemical disorder. In this paper, the properties, formation mechanisms and potential applications of HECs were summarized. The future research and development direction of HECs were also prospected. © 2023 Central South University of Technology. All rights reserved.
