The self-made Cu-RE refining agents were used to refine impure-copper. The influences of RE elements on refinements and structures were studied and the effect mechanism of RE was discussed. The results show that by adding proper amounts of Cu-RE refining agents into impure-coppers, the effect of RE on the refinement of impure-coppers is perfect. Furthermore, the dendrite grains of the samples are refined and the structure becomes more homogeneous, so the electric conduction function and mechanical properties of the impure-copper are improved.
