Solid oxide oxygen pump based on perovskite oxide and preparation method thereof
The invention discloses a solid oxide oxygen pump based on perovskite oxide and a preparation method of the solid oxide oxygen pump, and belongs to the technical field of ceramic preparation. Carrying out tape casting; hot pressed sintering; preparing symmetrical electrodes; and sintering the battery to obtain the finished oxygen pump. The water-based tape casting slurry is prepared by mixing in three times, for the first time, a solvent and a dispersing agent are fully mixed, then ceramic powder is added, dispersion of lanthanum strontium gallium magnesium dilute particles can be further promoted, the ceramic powder can be evenly dispersed in the solution, for the second time, a binder, a plasticizer and a lubricating agent are fully mixed and then mixed with the initial slurry, and the dispersion of lanthanum strontium gallium magnesium dilute particles can be further promoted. The uniform non-Newtonian fluid can be obtained, bubbles in the solution can be eliminated by adding a small amount of the surfactant for the third time, tiny physical holes in a ceramic sheet can be reduced, more uniform green body density is achieved, the densified oxygen pump is finally obtained by matching with the steps of hot pressing, sintering and electrode infiltration, and the mechanical strength and electrochemical performance of the oxygen pump are guaranteed.
本发明公开了基于钙钛矿氧化物的固体氧化物氧泵及其制备方法，属于陶瓷制备技术领域，包括：制备水基流延浆料；流延成型；热压烧结；对称电极制备；电池烧结，得到成品氧泵。本发明水基流延浆料分三次混合制备，第一次将溶剂与分散剂充分混合后再加入陶瓷粉体，能够进一步促进镧锶镓镁稀颗粒的分散，使陶瓷粉体能够均匀的分散在溶液内，第二次将粘结剂、塑化剂、润滑剂充分混合后再与初始浆料混合，能够得到均匀的非牛顿流体，第三次通过表面活性剂的少量添加消除溶液中的气泡，能够减少陶瓷片中微小物理孔，实现了更均匀的绿体密度，配合热压、烧结、电极浸润步骤，最终得到致密化氧泵，保证了氧泵的机械强度和电化学性能。
