| Abstract: | Effects of rare earth elements La, Ce, Y and ordinary charcoal composite refining technics on the microstructure and performance of red-copper have been studied. The results show that the composite refining technics can eliminate hydrogen, oxygen and other impurities, so it can improve the eligible proportion of red-copper products. The adding of rare earth La, Ce, Y all can improve the general performance of red-copper, among them the element Y has the best effect. |
