摘　　要：利用6 000 A稀土电解槽,在氟化锂—氟化钕熔盐体系中,通过熔盐电解制取金属钕,研究氟化锂含量、温度、阴极插入深度等对稀土电解过程的影响.研究结果表明,氟化锂的质量分数保持在8%左右,熔盐温度控制在1 050℃,阴极插入深度距钼锅为7 cm时最优.上述最佳工艺条件可有效提高产品质量,减少物料损耗,降低生产成本.Using 6000 A Rare Earth electrolytic cell,the metal neodymium was prepared by electrolyzing the molten salt system of lithium fluoride and neodymium fluoride.The influence of lithium fluoride,temperature and cathode penetration depth on the electrolytic process of Rare Earth was studied.The results show that the optimum concentration of lithium fluoride is about 8%,the temperature of molten salt should be controlled at 1050℃,and the best insertion depth of cathode is 7 cm away from the molybdenum pot.The above optimum technological conditions can effectively improve product quality,reduce material loss and reduce production cost.
