Magnetic α-Fe₂O₃, γ-Fe₂O₃ and Fe₃O₄ were prepared by facile calcination under different temperature from K₄[Fe(CN)₆] as raw materials, in which the calcined products are α-Fe₂O₃, Fe₃O₄ and γ-Fe₂O₃ at 400 or 700, 500, and 600℃, respectively. The as-prepared compounds were characterized by X-ray powder diffraction and scanning electron microscopy, and their magnetic behavior at room temperature was also studied. This method provided a simple approach to prepare different polymorphic forms of magnetic iron oxides, which may have potential applications in magnetic science, magnetic composite materials, magnetic core, magnetic separation and medical diagnostics.
