摘要：
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 areα-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.
