Resumen
The thermal decomposition of Y[Fe(CN)6]•4H2O has been studied in order to investigate the formation of the multi-ferroic oxide YFeO3. The starting material (Y[Fe(CN)6]•4H 2O) and the decomposition products were characterized by IR spectroscopy, thermal analysis, X-ray powder diffraction (PXRD), and scanning electron microscopy. Metastable YFeO3 with hexagonal structure, space group P6 3 /mmc, was obtained by thermal decomposition of Y[Fe(CN)6]•4H2O at 600 °C in air. Orthorhombic YFeO3 was obtained by the same method at T ≤ 800 °C in air. The crystal structure of orthorhombic YFeO3 was refined by Rietveld analysis using PXRD data. We found that it was slightly deficient in Y 3+, which is in agreement with the small amount of Y 2O3 found as impurity in the sample. The formula of the orthorhombic phase is Y0.986FeO3. © 2010 Akadémiai Kiadó, Budapest, Hungary.
