摘要：

The thermal decomposition products of Mohr's salt, (NH4)2Fe(SO4)2.6 H2O, in static air have been studied in the temperature range 25-800‡. Mössbauer spectroscopy, X-ray diffractometry and thermal analysis were used in the identification of the intermediates. Fe2+ compounds containing 4, 2 and zero H2O were identified and the possibility of occurrence of (NH4)2Fe2(SO4)3 is advanced. The presence of Fe3+ was detected starting at 230‡ for a 1.6‡/min heating rate, and the compounds (NH4)Fe(SO4)2 and Fe2(SO4)3 were also identified. © 1979 Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest.
