摘要
根据惯性约束聚变靶材料研究的需要采用自悬浮定向流技术制备了金属纳米Fe粉，通过透射电子显微镜和X射线衍射分析技术研究了颗粒的形貌、粒度和相组成。结果表明，所制备的纳米Fe粉为规则的球状颗粒，其粒径分布在30～70nm之间，在空气中颗粒表面有氧化膜生成，其氧化产物为Fe3O4。
Fe nanoparticles were prepared by flow-levitation method for physical doping of ICF target materials. The morphologies, granularities and structures of Fe particles were investigated by TEM, XRD techniques. The results show that the particles prepared by this means are spherical and the particle size can be controlled availably in 30-70 nm. In addition, it is discovered by XRD techniques that there appeared Fe3O4 oxide film generated in the air, adhering to the surface of the nanoparticles.
