A. Venkataraman, STUDIES ON HYDROGEN FERRITE PHASE IN GAMMA-FE2O3 SYNTHESIZED FROM FERROUS FUMARATE HALF HYDRATE PRECURSOR, Journal of thermal analysis, 46(1), 1996, pp. 219-224
Thermal techniques viz., TG/DTA/DSC methods have been employed in unde
rstanding the formation and decomposition of hydrogen ferrite phase (H
-F) as a metastable intermediate in the conversion of gamma-Fe2O3 . xH
(2)O, to alpha-Fe2O3. Magnetic hysteresis measurements carried out at
liquid N-2 and at room temperature for the vacancy ordered gamma-Fe2O3
and its H-F phase also supplement these studies.
