| Abstract: | Nanometer γ-Fe_2O_3 powder was fabricated through detonation and the characteristics of the powder were analyzed by TEM and X-ray diffraction.The analysis indicates that the γ-Fe_2O_3 is reddish brown,has perfect granule roundness and strong ferromagnetic property,of which the average diameter is 42.17nm.Detonation proves to be a convenient,shortcut and energy-saving way to synthesize nano-meter iron oxide in nanopowder preparation. |
