自科学院应用化学研究所采用液体铝阴极制取铝稀土中间合金获得成功以来,国内许多单位在铝电解槽中添加稀土氧化物,氯化物或稀土碳酸盐等原料制取铝稀土合金的工艺先后成功,并在工业上推广应用。由于稀土的变质作用,使这种合金的机械性能和 Since the Institute of Applied Chemistry, Institute of Applied Chemistry liquid aluminum cathode made of aluminum rare earth master alloy has been successful, many domestic units in the aluminum electrolytic cell to add rare earth oxides, chloride or rare earth carbonate and other raw materials obtained from aluminum rare earth alloy technology has Successful, and in the industrial promotion and application. Due to the metamorphism of rare earths, the mechanical properties of this alloy are
