High entropy ceramics (HECs) are a novel class of ceramics that exhibit high melting point, excellent high-temperature mechanical performance, and superb corrosion resistance, making them promising candidates for advanced nuclear reactors. Notably, encouraging irradiation tolerance has been found in a few HECs based on the scattered reports in the current literature. In this article, we systematically review the recent progress in the irradiation response of HECs, including high entropy carbides, high entropy pyrochlore oxides, high entropy MAX phases, and high entropy nitride films. The influence of chemical complexity on the irradiation properties of HECs is examined by comparing them with their corresponding single-component ceramic counterparts. Besides, the similarities and differences between HECs and widely-studied high entropy alloys are discussed regarding their irradiation responses. In the end, we envisage prospects for the future development of irradiation-tolerant HECs.

高熵陶瓷的辐照性能：与常规陶瓷和高熵合金的综合比较

高熵陶瓷（HEC）是一类新型陶瓷，具有高熔点、优异的高温机械性能和优异的耐腐蚀性，使其成为先进核反应堆的有希望的候选者。值得注意的是，根据当前文献中的零星报道，一些 HEC 已发现了令人鼓舞的辐照耐受性。在本文中，我们系统地回顾了HEC的辐照响应的最新进展，包括高熵碳化物、高熵烧绿石氧化物、高熵MAX相和高熵氮化物薄膜。通过将 HEC 与相应的单组分陶瓷对应物进行比较，研究了化学复杂性对 HEC 辐照性能的影响。此外，还讨论了 HEC 与广泛研究的高熵合金在辐照响应方面的异同。最后，我们展望了耐辐照HEC的未来发展前景。
