## Abstract The decomposition of ammonium heptamolybdate (AHM, (NH~4~)~6~Mo~7~O~24~Γ4H~2~O) was studied in situ by Xβray diffraction and Xβray absorption spectroscopy, as well as by thermal analysis (TG/DTA). Decomposition conditions such as reactant atmospheres, (20% oxygen, 5% propene, 5% hydroge
In this study, ammonium tetramolybdate (ATM) was obtained as the intermediate product of ammonium heptamolybdate tetrahydrate (AHM). The thermal decomposition mechanism of ATM was investigated under nonisothermal and isothermal conditions in air and inert gas atmospheres. Nonisothermal experiments w
