High-temperature-resistant wave-absorbing honeycomb ceramic as well as preparation method and application thereof
The invention discloses a high-temperature-resistant wave-absorbing honeycomb ceramic as well as a preparation method and application thereof, and relates to the technical field of porous ceramic materials. The method includes: acquiring a honeycomb skeleton; introducing a porous structure material to the honeycomb skeleton to obtain a honeycomb structure preform; introducing a ceramic phase on the honeycomb structure preform to obtain a porous compound; and removing the honeycomb skeleton in the porous compound to obtain the high-temperature-resistant wave-absorbing honeycomb ceramic. The prepared ceramic has a porous wall structure and a hollow framework, and mainly overcomes the defects that an existing high-temperature-resistant wave-absorbing ceramic honeycomb is complex in preparation process, poor in wave-absorbing performance, difficult to regulate and control and the like.
本发明公开了一种耐高温吸波蜂窝陶瓷及其制备方法和应用，涉及多孔陶瓷材料技术领域。包括获取蜂窝骨架；在所述蜂窝骨架上引入多孔结构材料，获取蜂窝结构预制体；在蜂窝结构预制体上引入陶瓷相，获取多孔复合物；将多孔复合物中的蜂窝骨架去除，获取耐高温吸波蜂窝陶瓷。本发明制得的陶瓷具有多孔壁结构以及中空骨架，主要解决现有耐高温吸波陶瓷蜂窝制备工艺复杂、吸波性能差且难以调控等缺点。
