Mössbauer characterization of calcium–ferrite oxides prepared by calcining Fe2O3 and CaO
- 199 Downloads
Calcium ferrite oxides were prepared by calcining a mixture powder of iron- and calcium oxide. The 57Fe-Mössbauer spectra of the calcium ferrites oxides were measured, revealing that the products should be Ca2Fe2O5 and CaFe2O4, the ratio of which was dependent of the Fe/Ca atomic ratio of the mixture powder.
