Abstract
A study by means of powder X-ray diffraction at high temperature of Ba 2Fe2O5 shows the existence of a monoclinic-cubic transition as a conse quence of the disappearance of the ordering of anionic vacancies in th e starting monoclinic material. A similar transition has been encounte red during transmission electron microscopy observations.
