【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15nm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.更多还原

【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.更多还原
