| Abstract: | The 11.3 nm diameter nanopowders of Ni dominated Ni(Fe) solid solution can be prepared by(using) aluminum powder to react with FeSO_4\5(NH_4)_2SO_4 and NiSO_4\5(NH_4)SO_4 mixed solution.In the product,the Fe atoms replaced parts of the Ni atoms.While the mass fraction of Ni~2 /(Fe~2 Ni~2 ) in the solution is higher than 76%,solid solution of homogenous phase Ni(Fe) can be obtained.If the content of Ni~2 /(Fe~2 Ni~2 ) lower than this point,the Ni(Fe) Fe or Fe Ni_0.36Fe_0.64 mixed phase nanopowders will be produced. |
