Boride-containing silicon carbide composite ceramic fiber and preparation method thereof
The invention discloses a boride-containing silicon carbide multiphase ceramic fiber and a preparation method thereof, active silicon-hydrogen bonds of polymetal carbosilane are utilized to react with boron trichloride gas in an electron beam excitation state, a boron element is introduced in a non-melting treatment process, and pyrolysis decarburization and high-temperature sintering are performed to obtain the boride-containing silicon carbide multiphase ceramic fiber. And thus, the silicon carbide fiber containing the metal boride is obtained. The multiphase ceramic fiber has excellent mechanical properties and high temperature resistance, and can be used as a reinforced phase material for preparing a ceramic-based composite material.
本发明公开了一种含硼化物的碳化硅复相陶瓷纤维及其制备方法，利用聚金属碳硅烷的活性硅氢键，在电子束的激发状态下，通过与三氯化硼气体反应，在不熔化处理过程中引入硼元素，并经过热解脱碳、高温烧成，从而得到含金属硼化物的碳化硅纤维。本发明的复相陶瓷纤维具有优异的力学性能和耐高温性能，可以用作制备陶瓷基复合材料的增强相材料。
