Title: Catalytic thermal decomposition of magnesium iodate in the presence of metal oxides or carbon
Abstract: The catalytic thermal decomposition of intimate mixtures of Mg(IO3)2 and metal oxides (Fe2O3, Fe3O4, Cr2O3) or C (active carbon) was investigated by employing thermogravimetry (TG), differential thermal analysis (DTA), X-ray diffraction analysis and gas chromatography. The initial decomposition temperature of the mixtures was around 720 K which was much lower than that of pure Mg(IO3)2, around 820 K. Fe2O3 showed no change. Fe3O4 was oxidized to Fe2O3. Cr2O3 reacted with Mg(IO3)2 to form MgCrO4. Active carbon also reacted with Mg(IO3)2 and was changed to CO and CO2.
