Synthesis of Fe2O3 nanoparticles in different reaction media

γ-Fe2O3 nanocrystallites were synthesized from iron(II) acetylacetonate using the solvothermal reaction and calcined at 500–900 °C. Their structure was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The crystallite size was calculated using the Scherrer equation. No influence of reaction medium was observed on the crystal growth rate during the γ → α-Fe2O3 phase transformation.
