摘要：
Perovskite type SrFeO3 is a suitable candidate for gas sensors and catalytic applications. It is very difficult to stabilize the stoichiometric SrFeO3, which is highly unstable because of the presence of Fe4+ ions that leads to the oxygen vacancies (delta) in order to maintain charge equilibrium. For delta = 0, 0.13, 0.27 and 0.5, it takes SrFeO3, SrFeO2.87, SrFeO2.73 and SrFeO2.5 phases respectively. The oxygen vacancy plays an important role in determining its structural and electronic properties. Nanocrystalline SrFeO3 has been prepared by thermal decomposition method and its structural, morphological, magnetic and electrical properties are analyzed.
