Introduction

The concept of entropy stabilization has created new opportunities for the design and discovery of novel ceramic materials for extreme environments. High-entropy ceramics (HECs) contain no less than four different elements in an equal or near-equal atomic ratio in the cation position, creating a high configurational entropy. Since 2015, various material systems of HECs have been synthesized including oxides, carbides, borides, nitrides, sulfides, and silicides. Their diversity in chemical composition, crystal structure, and electronic structure provides a huge space for tuning the physical properties such as hardness, thermal conductivity, ionic conductivity, irradiation resistance, and electromagnetic wave absorption, leading to promising applications in thermal barrier coatings, thermoelectrics, catalysts, batteries, etc.

The aim of this special issue is to provide an international forum for researchers to present the state-of-the-art development, challenges, and foresight visions in processing and characterizations of HECs, with an emphasis on their new properties and performance in extreme environments.


Possible topics, within this scope, include but are not limited to:

  •    New single phase or composite materials

  •    Novel synthesis and processing methods for powder, bulk, and coating

  •    Processing-microstructure-property relationship

  •    New characterization methods, such as in-situ technique

  •    Thermodynamics, first-principles simulation, and modelling

  •    Mechanical, thermal, electrical, and optical properties

  •    Response in extreme environments

  •    Methods for improving the physical properties
