Fluorinated phases formed by reaction of Fe0.5Co0.5Sb2O4 and Fe0.5Mg0.5Sb2O4 with gaseous fluorine have been examined by 57 Fe Mössbauer spectroscopy between 298 and 5 K. The degree of oxidation of Fe2+to Fe3 +has been used to quantify the amount of fluorine incorporated within the channels of the schafarzikite-related structure and enable the evaluation of the compositions as Fe0.5Co0.5Sb2O4F0.41...
New materials based on the composition of the mineral schafarzikite, FeSb 2 O 4 , have been synthesised. 5 7 Fe- and 1 2 1 Sb- Mössbauer spectroscopy shows that iron is present as Fe 2 + and that antimony is present as Sb 3 + . The presence of Pb 2 + on the antimony...
