High-Entropy Ceramics: A Mix-and-Match Approach to Material Design
High-entropy ceramics (HECs) are a new class of materials with diverse crystal structures and electronic configurations, enabling unique property combinations not found in traditional ceramics. These materials exhibit enhanced hardness, low thermal conductivity, and tunable thermal expansion, showing promise for applications ranging from thermal protection to energy storage and catalysis.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Limited Mechanical Property Data
Limited availability of mechanical property data like fracture toughness due to small sample sizes, hindering comprehensive property assessment and application development.
Simplified Computational Models
Reliance on simplified computational models for predicting formability, sacrificing accuracy for computational efficiency, may overlook crucial factors influencing stability.
Limited Multiphase Design Exploration
Scarcity of research on tuning properties through multiphase compositions and microstructures, which are crucial for many applications requiring balanced property profiles.
Limited Understanding of Thermal Expansion
Lack of in-depth understanding of the thermal expansion behavior of HECs and methods to tailor it for specific application requirements.
Balancing Properties for Cladding
Challenges in balancing irradiation resistance and thermal conductivity for cladding applications, needing further investigation and design strategies.
Brittleness of Some HECs
Brittle nature of some HECs, like high-entropy bixbyite-structured oxides, posing limitations for structural applications requiring high fracture toughness.
Oxidation Resistance Challenges
Limited data on high-temperature oxidation mechanisms and potential destabilization of solid solutions or formation of competing phases, necessitating careful composition design.
Thermal Shock Resistance
Thermal shock resistance as a concern for high-temperature applications, specifically the potential exacerbation due to glass-like low thermal conductivity.
Limited Research on HECs Fibers
Lack of research on HECs fibers despite their potential for high-temperature applications due to good strength, stability, and low thermal conductivity.
Limited Microstructure and Interface Engineering
Limited microstructure design and surface/interface modifications for enhancing performance in specific applications.
Rating Explanation
This review provides a comprehensive overview of the current status of high-entropy ceramics, covering various aspects from structure and properties to processing and applications. While the field is still in its nascent stages and faces several challenges, the novel design paradigm and potential for property tuning offer exciting possibilities. The rating of 4 reflects the strong research potential and promising directions but acknowledges the existing limitations and need for further investigation.
