Porous nitride ceramic and preparation method thereof
The invention provides porous nitride ceramic and a preparation method thereof, and belongs to the technical field of preparation of porous ceramic. The preparation method of the porous nitride ceramic comprises the following steps: mixing oxide powder, resin, an amine organic compound and a solvent to obtain slurry; dipping a porous organic template in the slurry, taking out and drying to obtain the dipped template; placing the dipped template in an inert gas environment to carry out degreasing reaction on an organic matter to obtain a ceramic precursor; and sintering the ceramic precursor in an inert gas environment to obtain the porous nitride ceramic. In the preparation process, the resin and the amine organic compound provide a carbon source and a nitrogen source through degreasing pyrolysis reaction and react with the oxide powder to obtain the nitride ceramic, molding and preparation of the ceramic material are completed in one step, and other sintering aids do not need to be added.
本申请提供一种多孔氮化物陶瓷及其制备方法，属于多孔陶瓷的制备技术领域。多孔氮化物陶瓷的制备方法包括：将氧化物粉末、树脂、胺类有机化合物和溶剂混合得到浆料。将多孔有机模板浸渍在浆料中后取出干燥得到浸渍模板。将浸渍模板置于惰性气体环境中使有机物进行脱脂反应以得到陶瓷前驱体。将陶瓷前驱体置于惰性气体环境中进行烧结得到多孔氮化物陶瓷。在制备过程中，树脂和胺类有机化合物通过脱脂热解反应提供碳源和氮源，与氧化物粉末发生反应，得到氮化物陶瓷，成型和陶瓷材料的制备一步完成，不需要添加其他烧结助剂。
