摘要
高熵陶瓷材料通常是指由五种或五种以上金属阳离子以等物质的量或近等物质的量组成的多组元固溶体。近年来,高熵陶瓷(High-entropy ceramics,HECs)由于具有单一的晶体结构和优异的物理化学性能,成为陶瓷领域的研究热点之一。本文介绍了国内外高熵陶瓷材料,如高熵碳化物、高熵氮化物、高熵氧化物、高熵硼化物、高熵硅化物和高熵硫化物的发展状况,总结了高熵陶瓷制备、结构性能与应用的研究工作,并对高熵陶瓷的发展方向和前景进行了分析和展望。
High-entropy ceramic materials usually refer to the multi-principal solid solution composed of five or more ceramic components in equal mole or nearly equal mole.In recent years,high-entropy ceramics(HECs)have gained considerable attention due to their single-phase crystal structure and excellent properties.In this paper,we review the research development of high-entropy ceramic materials,such as high-entropy carbide,high-entropy nitride,high-entropy oxide,high-entropy boride,high entropy-silicide and high-entropy sulfide at home and abroad,summarize preparation method,structural properties and application structures and properties of HECs.Furthermore,we also propose our view about the future development and prospect of high-entropy ceramics.
