Method for preparing oxide layered ceramic at low temperature
The invention belongs to the technical field of layered ceramic preparation, and discloses a method for low-temperature preparation of oxide layered ceramic, and the specific technical scheme is as follows: adding ceramic powder to be prepared into an organic solvent to form slurry, putting the first layer of slurry into molding equipment, and curing the first layer of slurry by a curing molding method to form a first layer of green body; placing the second layer of slurry on the first layer of green body, and curing the second layer of slurry to form a second layer of green body; repeating the steps to cure the slurry layer by layer to form a green body with an n-layer structure; then, the green body is dried and degummed at a certain temperature, current not smaller than 5 mA/mm < 2 > is applied to the green body at the temperature of 300-1300 DEG C and kept for 0.5-30 min, the green body is sintered into ceramic, an electric field can promote the diffusion rate of the material, rapid sintering of the ceramic material is achieved, and the temperature and time needed by sintering are reduced.
本发明属于层状陶瓷制备技术领域，公开了一种用于氧化物层状陶瓷低温制备的方法，具体技术方案为：将要制备的陶瓷粉体加入到有机溶剂中形成浆料，将第1层浆料置于成型设备中，通过固化成型法使第1层浆料固化，形成第一层坯体；将第2层浆料置于第一层坯体上，固化成型使第二层浆料固化，形成第二层坯体；重复上述步骤使浆料逐层固化，形成具有n层结构的坯体；然后，将坯体在一定温度下干燥排胶，在300℃‑1300℃的温度下，对坯体施加不小于5mA/mm2的电流，并保持0.5s‑30min的时间，使坯体烧结成陶瓷，电场可以促进材料的扩散速率，实现陶瓷材料的快速烧结，降低了烧结所需温度和时间。
