Preparation of Complex Phase Ultrafines with Nanometer Size by Using γ-ray Irradiation in a Mixed Solution Containing Ni²⁺ and Cu²⁺

In this paper the correspoinding complex phase ultrafines with nanometer size,which were prepared by using γ-ray radiationin a mixed solution containing Ni²⁺ and Cu²⁺ and their physicochemical process were reported.The authors also discussed the influence of irradiation conditions on composition,particale size,grain size of various complex phase ultrafines with nanometer size,such as,Cu-Cu₂O,Cu-Ni-Cu₂O,and Cu-Ni.
