Carbide high-entropy-SiC composite ceramic powder and preparation method thereof
The invention relates to the technical field of preparation of high-entropy compounds, in particular to carbide high-entropy-SiC composite ceramic powder and a preparation method thereof. The molecular formula of the carbide high-entropy-SiC composite ceramic powder is XC-SiC, wherein X is a combination of four or five elements of Hf, Nb, Zr, Ta and Ti in an equal molar ratio. The carbide high-entropy-SiC composite ceramic powder prepared by the method has low oxygen content, and has wide potential application value in the fields of energy, aviation, spaceflight and the like. According to the preparation method provided by the invention, the uniformity of each element on the molecular scale can be greatly improved, so that the preparation temperature can be reduced, meanwhile, equipment required by the method is simple, a series of multiphase ceramic powder can be obtained, and the powder has the advantage of high purity.
本发明涉及高熵化合物制备技术领域，尤其是涉及一种碳化物髙熵‑SiC复相陶瓷粉体及其制备方法。碳化物髙熵‑SiC复相陶瓷粉体，分子式为XC‑SiC其中X为Hf、Nb、Zr、Ta、Ti中的四种或五种元素等摩尔比组合。本发明制备得到的碳化物髙熵‑SiC复相陶瓷粉体具有较低的含氧量，在能源、航空及航天等领域具有广泛的潜在应用价值。本发明提供的制备方法能够大幅提升各元素在分子尺度上的均匀性，从而能够降低制备温度，同时该方法所需要的设备简单，能够获得系列化的复相陶瓷粉体，且粉体具有纯度高的优点。
