The Synthesis of Maghemite Nanoparticles by Thermal Decomposition of Cryochemically Modified Iron(III) Acetylacetonate

Maghemite nanoparticles of 40 to 150 nm are obtained by the thermal decomposition of preliminarily cryochemically modified iron acetylacetonate. The composition and structure of the obtained particles and cryomodified precursor salt are determined by the X-ray diffraction (XRD) analysis, thermoanalytical methods (thermogravimetry, differential scanning calorimetry), infrared spectroscopy, and transmission electron microscopy.
