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 very corrosion resistant to AlF3-NaF-Al2O3 melts under the conditions of anodic polarization; （2） High anodic current density（>1.5 A·cm-2）, high alumina concentration and low ratio of NaF/AlF3 in the molten salts would be the most important conditions for using inert anode.
