【 摘 要 】

A new combustion route for the synthesis of ð›�?-Fe₂O₃ is reported by employing purified ð›�?-Fe₂O₃ as aprecursor 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. ð›�?-Fe₂O₃. The as synthesized ð›�?-Fe₂O₃ is characterized employing thermal, XRD, SEM, magnetic hysteresis, and density measurements. The effect of ball-milling on magnetic properties is also presented.
