High-entropy carbide ceramic material as well as preparation method and application thereof
The invention discloses a high-entropy carbide ceramic material as well as a preparation method and application thereof. The preparation method of the high-entropy carbide ceramic material comprises the following steps: 1) preparing metal oxide powder and carbon powder into mixed powder; 2) pressing the mixed powder into a green body, carrying out carbon thermal reduction reaction, taking out the obtained clinker, grinding and sieving to obtain clinker powder; and 3) pressing the clinker powder into a clinker blank, and sintering in an electric field to obtain the high-entropy carbide ceramic material. The high-entropy carbide ceramic material has the advantages of large component space, high density, no oxide impurity phase, excellent mechanical property and the like, and the preparation method has the advantages of simplicity in operation, extremely short reaction time, low equipment requirement, simple process flow, low synthesis cost, low energy consumption and the like, is suitable for component screening and large-scale industrial production, and has wide application prospects. Wide application prospects are realized.
