| 摘 要： | 为了获得价廉而方便的制取Fe-Co纳米粉体的方法,在pH～3, 40 ℃条件下用铝粉还原FeSO4•(NH4)2SO4和CoSO4•(NH4)2SO4的混合溶液,制得了平均粒径为15 nm的Fe-Co固溶体粉体.用XRD鉴定了合金的物相和粒度,ICP方法分析了合金的成份.实验表明,固溶体的成份可以通过改变溶液中Fe2＋和Co2＋的比例而得以调整.

| Abstract: | A cost effective and convenient method for preparing nanopowders of Fe-Co alloy has been developed. The finely divided powders of Fe-Co alloy in the form of solid-solution were obtained in the FeSO4•(NH4)2SO4 and CoSO4•(NH4)2SO4 mixed solution by the reduction of aluminum powders at 40 ℃ and pH～3.The product of Fe-Co alloy was identified by XRD method and the calculated size of these nanoparticles was about 15 nm. Meanwhile, the compositions of obtained samples were analyzed by ICP-AES method. Experiment indicated that the composition of the alloy could be easily controlled by changing the mass ratio of Fe2＋:Co2＋ in the solution. |
