Resumen:
On the basis of previous studies about the pentacyanonitrosylmetallates whose thermal decomposition generates to different type of oxides, the Mn[Fe(CN)5NO]·2H2O was used as raw material to give FeMnO3. The decomposition of was studied by Thermogravimetric (TGA-DTG) and Differential Thermal Analysis (DTA) under air atmosphere, between room temperature and 1200°C. IR spectroscopy, and powder XRD refined by Rietveld analysis were used to follow the process. The XRD of the sample heated at different temperatures showed the following sequence: Fe3C, MnFe2O4 and (Mn,Fe)2O3 bixbyte phases, until arriving to the final product, MnFeO3.  Temperature programmed reduction (TPR) and EDS-EDAX analyses were used for the characterization, as well.
