The Electrochemical Reduction Mechanism of ZnFe2O4 in NaCl-CaCl2 Melts

The electrochemical reduction process of ZnFe2O4 in NaCl-CaCl2 melts was studied. Thermodynamic analysis shows that the is carried out multiple steps, and it difficult to reduce Fe3+ Fe one step. Electrochemical tests revealed includes three steps: First, reduced two then Zn2+ Zn on Mo electrode a reversible controlled by diffusion, while an irreversible diffusion. influence electrolysis voltage temperature electric deoxidation has also been It indicated properly increasing conducive diffusion oxygen ions, thereby rate. With gradual increase voltage, ? FeO + ZnO Zn.
