The invention discloses a hafnium carbide ceramic organic precursor as well as a preparation method and application thereof, and belongs to the technical field of hafnium carbide ceramic material preparation. The method comprises the following steps: in an inert gas protective atmosphere, adding a hafnium source into a carbon source, stirring, then adding alcohol, and reacting to obtain a reaction solution; and removing the solvent, and then drying to obtain a solid, namely the hafnium carbide ceramic organic precursor. The method disclosed by the invention has the characteristics of cheap, simple and easily available raw materials, simple process, short preparation period, low cost and high precursor molecular ceramic yield; the prepared product is novel in structure, good in dissolving property and suitable for preparing the impregnant of the ceramic modified carbon/carbon composite material, and has important application in the field of thermal protection materials such as spacecraft shells. The invention solves the problems of complex reaction route, high cost, low yield, impurity content and poor solubility of the method for preparing the HfC ceramic organic precursor in the prior art.
本发明公开了一种碳化铪陶瓷有机先驱体及其制备方法和应用，碳化铪陶瓷材料制备技术领域。该方法包括以下步骤：在惰性气体保护气氛中，将铪源添加到碳源中，搅拌，然后加入醇，反应，得到反应溶液；脱除溶剂，然后干燥，得到固体，即为碳化铪陶瓷有机先驱体。本发明方法具有原料廉价简便易得、工艺简单、制备周期短、成本低、先驱体分子陶瓷产率高的特点；制得产物结构新颖、溶解性能好，适用于制备陶瓷改性碳/碳复合材料的浸渍剂，在航天器外壳等热防护材料领域中有着重要的应用。本发明解决了现有技术中的制备HfC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。
