- Abstract
In this paper, a Ni0.36Al0.10Cu0.30Fe0.24 metallic inert anode was proposed and the electrochemical behaviors were studied in molten K2CO3-Na2CO3 at 1023 K by polarization curves and Tafel plots. The results indicated that Ni0.36Al0.10Cu0.30Fe0.24 alloy was stable in carbonate due to the formation of a passivation film on the surface. The film was mainly composed of NiFe2O4 and Al2O3 with a dense structure, which inhibited further corrosion of anode. Moreover, oxygen gas and Fe-Ni alloy have been successfully generated through electrolysis with NiO-Fe2O3 pellet as cathode and Ni0.36Al0.10Cu0.30Fe0.24 alloy as anode under a potential of 1.9 V for 24 hours. Ni0.36Al0.10Cu0.30Fe0.24 alloy exhibited bright prospect as a potential candidate of inert anode for green metallurgical process.
