Carbonitride superhigh-temperature ceramic precursor as well as preparation method and application thereof
The invention discloses a carbonitride superhigh-temperature ceramic precursor as well as a preparation method and application thereof, and relates to the technical field of superhigh-temperature ceramic materials. The method comprises the following steps: uniformly dispersing a transition metal chloride in an organic solvent under the protection of an inert atmosphere, adding a polyamine compound, carrying out a condensation reaction, adding a polyol compound, and carrying out an end capping reaction to obtain the carbonitride superhigh-temperature ceramic precursor. According to the invention, the MeC < x > N < 1-x > organic precursor is obtained by using atomic scale design. A precursor framework is formed by Me-N bond connection formed by transition metal Me and nitrogen element, so that the obtained precursor ceramic is high in yield and stable in material composition.
本发明公开了一种碳氮化物超高温陶瓷先驱体及其制备方法和应用，涉及超高温陶瓷材料技术领域。该方法包括在惰性气氛保护下，将过渡金属氯化物均匀分散于有机溶剂中，加入多胺类化合物，经缩合反应后，再加入多元醇类化合物，进行封端反应，得到碳氮化物超高温陶瓷先驱体。本发明利用原子尺度设计获得MeCxN1‑x有机先驱体。先驱体骨架是以过渡金属Me与氮元素形成Me‑N键连接而成，因此获得的先驱体陶瓷产率高，物质成分稳定。
