Effect of Rare Earth on Microstructure and Property of Refining Impure-Copper

Abstract:

The self-prepared Cu-RE refining agents were used to refine impure-copper. The influences of RE elements on refinements and structures were studied and the mechanism of RE was discussed. The results show that by adding proper amounts of Cu-RE refining agents into impure-coppers, the refinements of RE on impure-coppers are perfect. Furthermore, the dendrites of the RE-refined ingot are refined and the structure becomes more homogeneous, leading that the electric conduction function and mechanics function of impure-copper have been improved.
