在用电解法生产混合稀土金属时,有大量电解渣产出。遵照伟大领袖毛主席关于“综合利用大有文章可做”的教导,我厂用萃取法从电解渣中分离出纯度达70％以上的氯化钐。钐是钐钴合金的主要原料,钐钴合金作为永磁材料研究成功,已成为当前工业上重要的新型材料,可用于宇宙航行的行波管等,也用在电子手表及各种微波设备中。钐
Electrolytic production of mixed rare earth metals, a large number of electrolytic slag output. Following the teachings of Chairman Mao, the great leader, on “a great deal of comprehensive utilization can be done”, our factory separated the samarium chloride with the purity of over 70% from the electrolytic residue by the extraction method. Samarium is the main raw material of samarium-cobalt alloy. The successful research of samarium-cobalt alloy as permanent magnetic material has become the most important new material in the industry. It can be used in the traveling wave tube of cosmic navigation, etc., and also used in electronic watches and various microwave devices . samarium
