Synthesis of MnFeO<sub>3</sub> from the oxidate thermal decomposition of Mn[Fe(CN)<sub>5</sub>NO]·2H<sub>2</sub>O
On the basis of previous studies about the pentacyanonitrosylmetallates whose thermal decomposition generates different type of oxides, the Mn[Fe(CN)<sub>5</sub>NO]·2H<sub>2</sub>O was used as raw material to give FeMnO<sub>3</sub>. The decomposition was studied b...

| Sumario: | On the basis of previous studies about the pentacyanonitrosylmetallates whose thermal decomposition generates different type of oxides, the Mn[Fe(CN)<sub>5</sub>NO]·2H<sub>2</sub>O was used as raw material to give FeMnO<sub>3</sub>. The decomposition was studied by Thermogravimetric (TGA-DTG) and Differential Thermal Analysis (DTA) under air atmosphere, between room temperature and 1200°C. IR spectroscopy and XRPD, refined by Rietveld analysis, were used to follow the process. The XRPD of the sample heated at different temperatures showed the following sequence: MnFe<sub>2</sub>O<sub>4</sub> and (Mn,Fe)<sub>2</sub>O<sub>3</sub> disordered bixbyte phases, until arriving to the final product, MnFeO<sub>3</sub>. Temperature programmed reduction (TPR) and EDS-EDAX analyses were used for the characterization, as well. |
