Abstract

Amorphous iron oxide (Fe₂O₃) was prepared by the pyrolysis of iron pentacarbonyl [Fe(CO)₅] in a modified domestic microwave oven in refluxing chlorobenzene as a solvent under air. The reaction time was 20 min. Partially separated particles of iron oxide, 2-3 nm in diameter, were obtained. The other part showed aggregated spheres with a diameter of 25-40 nm. Differential scanning calorimetry measurements showed an amorphous/crystalline phase transition at about 250 °C.
