High-entropy boride ceramic material as well as preparation method and application thereof
The invention discloses a high-entropy boride ceramic material as well as a preparation method and application thereof. The preparation method of the high-entropy boride ceramic material comprises the following steps: 1) grinding at least four kinds of metal diboride powder in a protective atmosphere to obtain mixed powder; and 2) pressing the mixed powder into a green body, putting the green body into a box made of graphite paper coated with hexagonal boron nitride on the surface, embedding a graphite felt, putting the box in a protective atmosphere, electrifying the graphite felt, and performing electric field sintering on the green body to obtain the high-entropy boride ceramic material. The high-entropy boride ceramic material has the advantages of huge component space, uniform metal element distribution, adjustable performance and the like, and the high-entropy boride ceramic material is simple in synthesis process, extremely short in reaction time, low in equipment requirement, low in synthesis cost and beneficial to large-scale industrial production.
本发明公开了一种高熵硼化物陶瓷材料及其制备方法和应用。本发明的高熵硼化物陶瓷材料的制备方法包括以下步骤：1)将至少四种金属二硼化物粉体置于保护气氛中进行研磨，得到混合粉体；2)将混合粉体压制成生坯，再将生坯装入由表面涂覆六方氮化硼的石墨纸制成的盒子，再嵌入石墨毡，再置于保护气氛中将石墨毡通电对生坯进行电场烧结，即得高熵硼化物陶瓷材料。本发明的高熵硼化物陶瓷材料具有组分空间巨大、金属元素分布均匀、性能可调控等优点，且其合成工艺简单、反应时间极短、设备要求低、合成成本低，有利于进行大规模工业生产。
