在UCl_3-LiCl-KCl熔盐体系中，研究了钼、石墨和玻碳阳极在电解氯化铀过程中的电化学行为。钼阳极的循环伏安数据表明，钼阳极的腐蚀可通过钼化合物的形成或溶解来实现。而石墨阳极和玻碳阳极的实验数据表明，电解过程中氯的析出从1.2V开始，阳极电位保持稳定。因此，石墨和玻璃碳可以用作高温处理的电积过程中的惰性阳极。
The electrochemical behaviors of the molybdenum, graphite, and glassy carbon anode have been observed during the electrolysis of uranium chloride in an UCl3–LiCl–KCl molten salt. The cyclic voltammogram data of the molybdenum anode showed that Mo anode could be corroded by the formation of Mo compounds or its dissolution. However, the experimental data of the graphite and the glassy carbon anode showed that the chlorine evolution started from 1.2 V and the anode potential remained stable during uranium electrolysis. Therefore, the graphite and glassy carbon may be used as an inert anode in the electro-winning process of pyroprocessing.
