In 2015, a team led by S. Curtarolo and J.P. Maria transplanted the concept of “high-entropy” from alloys into the ceramic domain, giving rise to a new class of materials named “high-entropy ceramics” (HECs, also known as “compositionally complex ceramics”) [1,2]. A variety of novel HECs, including high-entropy oxides (HEOs), high-entropy diborides, high-entropy carbides, high-entropy nitrides (HENs), and high-entropy carbonitrides, have been developed since then [3]. The short-range chemical complexity in these materials, resulting from diverse species occupying identical crystallographic sites, implies a configurational disorder that can lead to unprecedented properties surpassing those of their non-disordered counterparts. Consequently, HECs have garnered great research interest over the past decade due to their exceptional thermal, mechanical, electrical, magnetic, optical, catalytic, electrochemical, and corrosion and radiation resistance properties, along with certain biological characteristics [[4], [5], [6]]. The boundless compositional space, unique microstructures, and versatile performance also render them very promising in broad applications ranging from structural components for engines and nuclear reactors to electronic and energy storage devices. To bring the recent advances in HECs to a wide audience, we organized this special issue in the Journal of Materiomics (JMAT).

 高熵陶瓷


2015年，由S. Curtarolo和J.P. Maria领导的团队将“高熵”的概念从合金移植到陶瓷领域，产生了一类名为“高熵陶瓷”（HEC，也称为“成分复杂陶瓷”）的新型材料[1,2]。从那时起，人们开发了多种新型 HEC，包括高熵氧化物 （HEO）、高熵二硼化物、高熵碳化物、高熵氮化物 （HEN） 和高熵碳氮化物 [3]。这些材料中的短程化学复杂性是由于不同的物种占据相同的晶体学位点而产生的，这意味着一种构型无序，这可能导致前所未有的特性超过它们的非无序对应物。因此，由于其卓越的热、机械、电、磁、光学、催化、电化学、耐腐蚀和耐辐射特性，以及某些生物学特性[[4]、[5]、[6]，HEC在过去十年中引起了极大的研究兴趣。].无限的组成空间、独特的微观结构和多功能性能也使它们在从发动机和核反应堆的结构部件到电子和储能设备的广泛应用中非常有前途。为了将 HEC 的最新进展带给广大读者，我们在《材料组学杂志》（JMAT） 上组织了本期特刊。
