| 摘 要： | 用X－射线衍射（XRD）和透射电子显微镜（TEM）等研究了不同水／表面活性剂（W]/S]）比的微乳液制备纳米Ni-Fe复合微粒的组成和粒径分布，结果表明，(W]/S]）比值不同，得到的Ni-Fe复合物微粒不但粒径不同，而产物的组成也有差异，当(W]/S]）＞240时，微粒粒径最小，但组成复杂；当(W]/S]）＜198时，微粒粒径呈寺大，但组成较单一，且可得到Ni-Fe合金相，各样品磁参数的测量表明，当将Ni-Fe组分总量规一化时，发现随Ni/Fe比增加，磁参数减小。

| Abstract: | The Composition and Size distribution of particles for prepare Ni-Fe composite nanoparticles with the W/O microemulsion method of different Water/Surfactant(/) by XRD and TEM have been investegated.It is shown that the Size and Composition of nanoparticles will change as / ratio.When />240, the Size of particles are small,but the composition is complex;When /<18, though the Size of particles are increase,but the composition is single,and shall may obtained the Ni-Fe ally.It is find that when Ni-Fe component is normalization by measure of magnetic parameters the whice are reduce as the Ni/Fe ratio raise. |
