| Outline of Final Research Achievements |
We investigated crytal structure and oxygen vacancy formation of SrFeO3-d using single crystal/powder neutron diffraction and X-ray diffraction method. It was found that the crystal symmetry of the SrFeO3-d was monoclinic, which was different from the reported one. With increasing tempeartature, oxygen vacancies were preferably created at the specific O sites.
We prepared a SrFeO3-d ceramics, whose grains were mostly oriented along c-axis. The oxygen permeation flux of the grain oriented sample was higher than that of the non-oriented sample.
