| Abstract: | The electrochemical stability of ZnFe2O4-based anode in Na3AlF6-Al2O3(saturated) melt was examined at 960.The relationship of current density and the over voltage of oxygen evolution on the ZnFe2O4-based anode was determined to be =0.12 0.052 logi(i=0.015-0.44A/cm2).The I-V curve on the ZnFe2O4-based anode was easured using potential scanning method. |
