Synthesis, properties, and applications of high-entropy oxide ceramics: Current progress and future perspectives

Abstract

High-entropy material (HEM) have played a significant role in the current research due to their novel composition with their synergistic elemental interactions resulting in enhanced functional properties. By creating an environment for a diverse range of chemical compositions, HEMs offer unique opportunities for novel materials with superior properties compared to conventional materials. There has been a special focus on high-entropy materials, especially oxides. HEMs possess fundamentally distinct properties that have led to a wide range of applications within a variety of research fields. The current review article gives a thorough insight into the idea of High-Entropy oxide (HEO) materials along with their synthesis, properties, and functional application. A review of recent state-of-the-art publications is used exclusively to provide an overview of the current scientific breakthroughs and challenges that exist in the high entropy oxide system. This provides an overview of the subject and facilitates the design of several different high-entropy oxide systems. The article concludes by discussing how high-entropy oxide ceramics will be used in diverse applications in the future.
