(ZrTiCoNb) C high-entropy carbide ceramic material and preparation method thereof
The invention belongs to the technical field of high-entropy ceramic materials, and discloses a (ZrTiCoNb) C high-entropy carbide ceramic material and a preparation method thereof. The preparation method comprises the steps that mixing a zirconium source, a titanium source, a cobalt source, a niobium source and a carbon source evenly through mechanical grinding, and obtaining a mixed powder; and then pre-pressing the obtained mixed powder into a blank, and carrying out microwave sintering at 1200-2000 DEG C for 1-2 hours to obtain the high-entropy carbide ceramic material. The method disclosed by the invention is low in synthesis cost and high in synthesis efficiency, and the high-entropy carbide ceramic material prepared by the method disclosed by the invention has relatively low oxygen content and relatively fine grain size.
本发明属于高熵陶瓷材料技术领域，公开了一种(ZrTiCoNb)C高熵碳化物陶瓷材料及其制备方法，所述制备方法包括：将锆源、钛源、钴源、铌源以及碳源通过机械研磨混合均匀，获得混合粉体；随后将获得的混合粉体预压制坯后，于1200～2000℃微波烧结1～2h，即得高熵碳化物陶瓷材料。本发明方法合成成本低且合成效率高，且通过本发明方法制得的高熵碳化物陶瓷材料，具有较低的氧含量以及较细的晶粒尺寸。
