中文摘要：
利用爆轰合成的方法制备纳米γ-Fe2O3粉末，采用透射电镜以及X射线衍射等检测方法，对爆轰产物的形貌以及组成进行分析。研究结果表明，所制备的纳米γ-F32O3颗粒圆整度较高，呈现红棕色，经计算，产物平均粒径为42．17nm。爆轰法在材料制备中的应用，为纳米γ-Fe2O3的合成提供了简便、快捷而又节省能源的新方法。
英文摘要：
Nanometer γ-Fe2O3 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-Fe2O3 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.
