The invention discloses a metal carbide/silicon carbide multiphase ceramic organic precursor as well as a preparation method and application thereof, and relates to the technical field of multiphase ceramic preparation. The method comprises the following steps: in an inert atmosphere, adding a metal carbide precursor and liquid hyperbranched polycarbosilane into a cosolvent, stirring at room temperature, and removing the solvent by reduced pressure distillation to obtain a solid, namely the metal carbide/silicon carbide multiphase ceramic organic precursor. The preparation method has the characteristics of simple and easily available raw materials, simple process, short preparation period, low cost, novel precursor molecular structure, controllable ceramic phase composition, good high-temperature oxidation resistance, high ceramic yield and good solubility. The invention solves the problems of complex reaction route and poor product performance and solubility of the method for preparing the multiphase ceramic organic precursor in the prior art.
本发明公开了一种金属碳化物/碳化硅复相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：在惰性气氛下，将金属碳化物先驱体和液态超支化聚碳硅烷加入共溶剂中，于室温条件下搅拌，采用减压蒸馏脱除溶剂，得到固体，即为金属碳化物/碳化硅复相陶瓷有机先驱体。本发明具有原料简便易得、工艺简单、制备周期短、成本低、先驱体分子结构新颖、陶瓷相组成可控、高温抗氧化性能好、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制备复相陶瓷有机先驱体的方法反应路线复杂以及产品性能和溶解性差的问题。
