ABSTRACT
The effect of the Fe2+B/Fe3+B ratio (the ratio of divalent and trivalent iron ion in B position of the inverse spinel structure) in cermets on the electric conductivity and corrosion resistance of anodes was investigated. The experimental results showed that both the electrical conductivity and corrosion resistance are proportional to the Fe2+B/Fe3+B ratio on the surface of anodes because FeAl2O4 and NiAl2O4 are produced on the surface of the anode and Fe3+ in the NiFe2O4 is corroded preferentially during electrolysis.
