Abstract
Synthetic iron-containing leucite-type phases have been studied using Fe-57 Mossbauer spectroscopy in combination with X-ray absorption spec troscopy (XAFS and XANES). The Mossbauer and XAS data confirm that bot h Fe2+ and Fe3+ occupy tetrahedrally coordinated framework sites in th e synthetic phases. In addition, information on Fe2+/Fe3+ ratios, cati on site occupancies and first shell bond lengths has also been obtaine d.
