Oxide ceramic based on oxygen vacancy defect regulation and preparation method thereof
The invention relates to an oxide ceramic based on oxygen vacancy defect regulation and a preparation method thereof. The preparation method of the oxide ceramic based on oxygen vacancy defect regulation and control comprises the following steps: mixing a Magneli phase sintering aid containing oxygen vacancy defects with oxide ceramic raw material powder under an oxygen-free condition to obtain an oxide ceramic mixed raw material, drying, sieving, molding into a biscuit, sintering, and post-processing to obtain the oxide ceramic based on oxygen vacancy defect regulation and control. The oxide ceramic based on oxygen vacancy defect regulation and control is obtained; the total mass of the Magneli phase sintering aid containing the oxygen vacancy defect and the oxide ceramic raw material powder is 100%, the mass ratio of the Magneli phase sintering aid containing the oxygen vacancy defect is 0.5-10%, and the mass ratio of the oxide ceramic raw material powder is 90-99.5%.
本发明涉及一种基于氧空位缺陷调控的氧化物陶瓷及其制备方法。所述基于氧空位缺陷调控的氧化物陶瓷的制备方法包括以下步骤：在无氧条件下将含有氧空位缺陷的Magneli相烧结助剂与氧化物陶瓷原料粉体混合得到氧化物陶瓷混合原料，经干燥、过筛后成型为素坯，经烧结、后处理，得到所述基于氧空位缺陷调控的氧化物陶瓷；以含有氧空位缺陷的Magneli相烧结助剂与氧化物陶瓷原料粉体的总质量为100％计，含有氧空位缺陷的Magneli相烧结助剂的质量占比为0.5‑10％，氧化物陶瓷原料粉体的质量占比为90‑99.5％。
