Silicon carbide-boron nitride gradient composite ceramic as well as preparation method and application thereof
The invention relates to silicon carbide-boron nitride gradient composite ceramic and a preparation method and application thereof.The silicon carbide-boron nitride gradient composite ceramic has the advantages that silicon carbide second-phase compounding is introduced, gradient ceramic design is performed, and simple and convenient preparation of a boron nitride ceramic composite material can be achieved under the conditions that sintering aids do not need to be added and large sintering pressure does not need to be applied; meanwhile, the mechanical property can be effectively improved, and the high-temperature performance of the boron nitride ceramic material is guaranteed, so that the requirements of complex use environments such as side sealing plates are met.
本发明涉及一种碳化硅‑氮化硼梯度复合陶瓷及其制备方法和应用，本发明通过引入碳化硅第二相复合并进行梯度陶瓷的设计，在无需添加烧结助剂及施加很大烧结压力的情况下，可以实现氮化硼陶瓷复合材料简单便捷的制备，同时可有效提高其力学性能并保障氮化硼陶瓷材料的高温性能，从而满足侧封板等复杂使用环境的要求。
