【摘要】 研究了不同稀土元素对紫杂铜精炼效果的影响。结果表明,添加适量的稀土元素Y、La、Ce有利于提高紫杂铜的导电性能和力学性能,作用效果以Y为佳,其次为La、Ce。当稀土添加量超过0 15%时,其电导率和伸长率随添加量的增加而降低。更多还原

【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.更多还原
