Keywords: high-entropy ceramics (HECs); processing; structure; properties; applications 1 Introduction High-entropy ceramics (HECs) are solid solutions of inorganic compounds with one or more Wyckoff sites shared by equal or near-equal atomic ratios of multi- principal elements. This concept is ...
[13]. For examples, as the structural complexity and the consequent disorder contribute to the phonon scattering, high entropy ceramics show low amorphous-like thermal conductivity, promoting the thermal and environmental barrier protection [99–101]. Meanwhile, their mechanical properties can also be ...

In this paper, the development in the new field of high-entropy ceramics is reviewed with a special attention on principles, historical and publication trends, crystal structure, theoretical/empirical design, production methods, properties and potential applications. Moreover, a summary of publications ...
Entropy-related phase stabilization can allow compositionally complex solid solutions of multiple principal elements. The massive mixing approach was originally introduced for metals and has recently been extended to ionic, semiconductor, polymer and low
