碳或石墨通常用于熔融盐电解中的阳极材料，但是它们通过与浴中残留的O2-的电化学反应而被消耗。在723 K的LiCl-KCl-ClO熔体中，研究了不同结构的碳材料在含氧氯化物熔体中的阳极行为。研究了SiC在镀液中的阳极行为。在所有材料中，CO2和CO 32-发生反应，电极被消耗;石墨化度对石墨材料的消耗影响较小，GC的消耗最低。虽然SiO2在SiC材料上形成，但不能完全阻止SiC的消耗。SiC表面SiO2层的不均匀性可能导致SiC的消耗。
Carbon or graphite is commonly used to anode material in molten salt electrolysis, but they are consumed by a electrochemical reaction with a residual O2-in the bath. In this study, the dependence of anodic behavior in molten chloride containing O2-on some carbon materials with different structure has been investigated in LiCl-KCl-ClO melts at 723K. The anodic behavior of SiC was also investigated in the bath. In all materials, reactions of CO2 and CO3 2-occurred, and electrodes were consumed; a graphitization degree slightly influenced the consumption at graphite material, and the consumption of GC seemed the lowest. Although SiO2 was formed on SiC material, the consumption of SiC was not prevented completely. The unevenness of SiO2 layer on SiC might cause the consumption of SiC.
