铬-铁（CrFe）二元合金最近被提出用作熔融氧化物电解（莫伊）的“惰性”阳极。本文通过实验观察和理论计算，研究了阳极极化对莫伊腐蚀环境中CrFe阳极物理性能和功能性能的影响。研究结果表明，合金内部形成了一个由MgCr 2 O 4尖晶石层覆盖的铬铝固溶体。对检测到的氧化物的电性能的调查表明，层状氧化物垢在高温下起着有效的导电体的作用。并对氧化物的形成机理进行了探讨。
Chromium–iron (CrFe) binary alloys have recently been proposed to serve as the “inert” anode for molten oxide electrolysis (MOE). Herein, the effects of anodic polarization on physical and functional properties of CrFe anodes in the corrosive environment of MOE are studied via empirical observations and theoretical calculations. The findings indicate that the alloys form an inner chromia–alumina solid-solution covered by an MgCr2O4spinel layer. A survey into the electrical properties of the detected oxides suggests that the layered oxide scale function as an efficient conductor of electricity at elevated temperature. The formation mechanism of the oxides is also investigated.
