Inert anode has been a hot issue in the aluminum industry for many decades. In this article, with the help of FEA (finite element analysis) software Ansys, a model was developed to simulate the thermal stress distribution working condition of an inert anode. To reduce its thermal stress, the effect ...

(Cu-Ni)/(10NiO-90NiFe2O4) cermet inert anodes containing metal Cu-Ni 0, 5, 10, 15 and 20 wt% were prepared and their corrosion behavior in Na3AlF6-Al2O3 melts was investigated. The results indicate that the content of metal Cu-Ni has little effect on the steady-state concentration of Ni in electroly...
