The cubic-shaped pure iron particles with particle size ranging from 500 nm to 1.3 μm have been fabricated using a solvothermal method in ethanol solution.The controlled morphology and size distribution can be easily tuned by adjusting the reaction temperatures from 100 to 150 ℃.The uniform products with narrow size distribution and good dispersion can be prepared under 120 ℃(seen in Figure 1).These chemically synthesized Fe particles exhibit good air stability and very slight surface oxidation is observed in the as-synthesized samples.High saturation magnetization of 208-211 A·m2/kg can be achieved in these micron-level iron particles due to their pure α-Fe phase and very slight surface oxidation.The relative simple preparation process with low cost,good air stability and high saturation magnetization for these micron-sized pure iron particles promise their great potential applications in complicated shape and miniaturized Fe-based composite magnetic components.
