摘要：
ZnFe2O4-based inert anodes were made to conduct the aluminum electrolysis tests. The corrosion behaviors of the inert anodes were examined and discussed. Experiment results prove that: (1) ZnFe2O4-based inert anodes are good corrosion resistant to AlF3-NaF-Al2O3 melts under the conditions of anodic polarization; (2) High anodic current density (> 1.5 A center dot cm(-2)), high alumina concentration and low ratio of NaF/AIF(3) in the molten salts will be the most important conditions for using inert anode.
