Preparation method of rapidly sintered porous ceramic
The invention discloses a preparation method of rapidly sintered porous ceramic, which comprises the following steps: 1, weighing a ceramic main material and additives such as an adhesive, and uniformly mixing to form a mixture; 2, treating the mixture obtained in the step 1 to form a solid mixture or slurry; 3, filling a mold cavity with the solid mixture or slurry obtained in the step 2, and forming a green body through dry powder pressing or casting molding; and 4, firing the green body obtained in the 3, setting the firing air pressure to be 10<-3>-10<5> Pa and the temperature to be lower than 1000 DEG C, and thus obtaining the porous ceramic. The air pressure condition of 10<-3 >-10<5> Pa is set in the firing process in the porous ceramic preparation process, so that the firing process is completed within 4 hours at the temperature of lower than 1000 DEG C, the bending strength of the porous ceramic is ensured and even improved while the firing period is shortened, and the oxidation of the main material is inhibited.
本发明公开了一种快速烧结多孔陶瓷的制备方法，包括步骤一：称取陶瓷主料及粘合剂等添加剂，混合均匀形成混合物；步骤二：处理步骤一所得混合物形成固体混合物或浆料；步骤三：将步骤二所得固体混合物或浆料填入模腔，通过干粉压制或浇注成型形成坯体；步骤四：对步骤三所得坯体进行烧制，设置烧制气压为10‑3～105Pa，温度低于1000℃，制得多孔陶瓷。通过在多孔陶瓷制备工艺中的烧制工艺设置气压条件10‑3～105Pa，使烧制工艺在低于1000℃温度条件下4h内完成，缩短烧制周期的同时保证甚至提高多孔陶瓷的抗弯强度、抑制主料氧化。
