Abstract: A new combustion route for the synthesis of γ-Fe 2 O 3 is reported by employing purified a-Fe 2 O 3 as a precursor in the present investigation. This synthesis which is similar to a self propagation combustion reaction, involves fewer steps, a shorter overall processing time, is a low energy reaction without the need of any explosives, and also the reaction is completed in a single step yielding magnetic iron oxide i.e. γ-Fe 2 O 3 .The as synthesized γ-Fe 2 O 3 is characterized employing thermal, XRD, SEM, magnetic hysteresis, and density measurements. The effect of ball-milling on magnetic properties is also presented. |
