Thermal decomposition of iron oxychloride as studied by thermal analysis, X-ray diffraction and Mössbauer spectroscopy

57 Fe Mössbauer spectroscopy, X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), and differential thermal analysis (DTA) have been used to investigate the thermal decomposition behavior of iron oxychloride. Upon heating of FeOCl in air for a long time, the compound is decomposed aroun...

More Information
Summary:57 Fe Mössbauer spectroscopy, X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), and differential thermal analysis (DTA) have been used to investigate the thermal decomposition behavior of iron oxychloride. Upon heating of FeOCl in air for a long time, the compound is decomposed around 376 °C and turns into Fe 2O 3 and FeCl 3.
