| 摘要: 采用质量损失法、碘量滴定法和正电子湮没寿命谱研究了La2NiO4+δ透氧膜的非化学计量,并表征了该材料的氧渗透性能,探讨了La2NiO4+δ的非化学计量缺陷与氧渗透性能之间的关系。研究结果表明,La2NiO4+δ的氧渗透通量随δ的增大而增大。 |

| Abstract: Oxygen stoichiometry of La2NiO4+δ was determined by thermogravimetric analysis, iodometry and positron annihilation lifetime spectra analysis, and oxygen permeating flux was measured. The relationship between nonstoichiometry and oxygen permeability in La2NiO4+δ was discussed. The results show that oxygen permeating flux increases with increasing the extra exygen content (δ ). |
