The invention discloses a high-entropy ceramic organic precursor as well as a preparation method and application thereof, and relates to the technical field of composite ceramic preparation. The method comprises the following steps: in an inert gas shielding atmosphere, adding a titanium source, a zirconium source, a niobium source, a hafnium source and a tantalum source into a carbon source, stirring, then adding alcohol, reacting, removing a solvent, and then drying in vacuum to prepare the (Ti0. 2Zr0. 2Nb0. 2Hf0. 2Ta0. 2) C high-entropy ceramic organic precursor, namely the high-entropy ceramic organic precursor. The preparation method has the characteristics of cheap, simple and easily available raw materials, simple process, short preparation period, low cost, novel precursor molecular structure, high ceramic yield and good solubility. The invention solves the problems of complex reaction route, high cost, low yield, impurity content and poor solubility of the method for preparing the high-entropy ceramic organic precursor in the prior art.
本发明公开了一种高熵陶瓷有机先驱体及其制备方法和应用，涉及复相陶瓷制备技术领域。该方法包括以下步骤：在惰性气体保护气氛中，将钛源、锆源、铌源、铪源和钽源添加到碳源中，搅拌，然后加入醇，反应，脱除溶剂，然后真空干燥，制得(Ti0.2Zr0.2Nb0.2Hf0.2Ta0.2)C高熵陶瓷有机先驱体，即为高熵陶瓷有机先驱体。本发明具有原料廉价简便易得、工艺简单、制备周期短、成本低、先驱体分子结构新颖、陶瓷产率高以及溶解性能好的特点。本发明解决了现有技术中的制备高熵陶瓷有机先驱体的方法反应路线复杂、成本高、产率低、含杂质以及溶解性差的问题。
