The precursor was synthesized by sol-gel method with the reaction of MnSO4· H2O and (NH4)2Fe(SO4)2· 6H2O. The product was obtained by heat treatment at 400℃~600℃for 1h respectively.The properties and structures of material were char-acterized by XRD, IR and UV-vis, and its thermal analysis was studied by TG/DTA.The results show that the product of the α-Fe2 O3 nanoparticles are hexagonal crystal system , and the product obtained at 500℃has excellent magnetic properties .
