摘　　要：采用气-液反应法合成了纳米级铁粒子,利用TEM、XRD、VSM等仪器对合成产物的晶态、物相、形貌、粒度和磁性进行了表征。结果表明,合成的产物为纳米级α-Fe,且粒子被均匀地包覆了表面活性剂,抗氧化性能明显提高。粒子的平均粒径为17.2nm,饱和磁化强度为113.57A·m2/kg,磁性能相对稳定。Iron nanoparticles were synthesized by vapor-liquid and crystal state, phsical phase, mirograph, particle size and magnetic properties were characterized systematically by means of TEM,XRD and VSM etc. The results show that the product was orFe nanoparticles coated symmetrically with the surface activator and the properties of anti-oxidation was improves disinctly. Mean particle size is 17. 2nm,M, is 113. 57A ?m2/kg and magnetic properties is relatively stable.
