| Abstract: | The paper describes the research on the effect of different kinds of Rare Earth in red-impure-copper's?refinement. The results show that adding proper Rare-Earth elements like Y, La, Ce do good to improve the electrical conductivity and the mechanial properties of red-impure-copper. Y comes best on effects, then La and Ce. When the addition of Rare-Earth element is above 0.15%, the electrical conductivity and elongation will reduce as the addition increases. |
