一、前言 根据目前我国稀土和铝电解生产的实际情况,采用现行铝电解工艺,在电解质体系中添加部分稀土氧化物,经一次熔盐电解,使稀土与铝在阴极上同时析出,直接得到稀土铝合金是一种既经济又合理的方法。因此,对在工业铝电解槽上添加稀土氧化物直接生产铝基稀土合金进行了研究。该工作在国内较全面的基础研究首先是在东北工学院和长春应用化学研究所于1981年合作进行 I. Preface According to the current actual situation of rare earth and aluminum electrolysis in our country, the current aluminum electrolysis process is adopted to add part of rare earth oxide in the electrolyte system. After a molten salt electrolysis, rare earth and aluminum are simultaneously precipitated on the cathode to directly obtain rare earth Aluminum is an economical and reasonable method. Therefore, the direct production of aluminum-based rare earth alloys by adding rare earth oxides on industrial aluminum electrolyzers was studied. The work in the country more comprehensive basic research is first in Northeast Institute of Technology and Changchun Institute of Applied Chemistry in 1981 to carry out cooperation
