Abstract

Thermal techniques viz., TG/DTA/DSC methods have been employed in understanding the formation and decomposition of hydrogen ferrite phase (H-F) as a metastable intermediate in the conversion of γ-Fe2O3·xH2O, to α-Fe2O3. Magnetic hysteresis measurements carried out at liquid N2 and at room temperature for the vacancy ordered γ-Fe2O3 and its H-F phase also supplement these studies.
