Ştefănescu, O. Ştefănescu, M. Stoia, C. Lazau] In this paper we present a study on the synthesis of Fe(III) oxide, by thermal decomposition of some complex combinations of Fe(III) with carboxylate type ligands, obtained in the redox reaction between some polyols (ethylene glycol (EG), 1,2-propane diol (1,2PG), 1,3-propane diol (1,3PG) and glycerol (GL)) and NO3 - ions (from ferric nitrate). Fe2O3 was obtained by thermal decomposition of the synthesized metal-organic precursors at low temperatures. γ-Fe2O3 was obtained as nanoparticles at 300°C, while at higher temperatures α-Fe2O3 starts to crystallize and becomes single phase at ~500°C. The formation of the metal-organic precursors and their thermal decomposition were studied by thermal analysis and FTIR spectroscopy. The evolution of Fe2O3 crystalline phases with the thermal treatment of iron complexes was followed by RX diffractometry. The size of γ-Fe2O3 nanoparticles was estimated by transmission electron microscopy (TEM).
