Four Fe(III) chelates of different ligands (azodyes and Schiff bases) were prepared and characterized by different physico-chemical methods. The pyrolytic temperatures of these chelates were found out by thermo gravimetric analysis. These Fe(III) chelates were converted to nano sized Fe(III) oxides by thermal decomposition method. The nano Fe(III) oxides were characterized by FTIR, and XRD techniques, confirmed the formation of ?-Fe2O3 and ?-Fe2O3. Analysis of SEM and TEM was carried out to study the morphology and particle size. The results showed that the particles obtained from the thermal analysis of the iron chelates were nano sized ? and ? variety of Fe2O3. It is once again confirmed from the VSM measurements.
