300 A BENCH-SCALE ALUMINUM ELECTROLYSIS CELL WITH Fe-Ni-Al2O3 COMPOSITE ANODE
Light Metals 2005 Edited by Halvor Kvande TMS (The Minerals, Metals & Materials Society), 2005 ，-0001，（）：
A new Fe-Ni-Al2O3 metal matrix composite material was developed for aluminum electrolysis cells. A 300 A experiment for these anodes was operating with wettable cathodes (TiB2) at 960℃ for 10 h. The electrolyte consisted of 51NaF-39AlF3- 3CaF2-7Al2O3(wt%). The potential from the anode to the aluminum reference electrode was 2.25V. The purity of the produced aluminum was <99% with 75% current efficiency. After electrolysis, the SEM analysis indicated that there was a layer consisting of Al2O3 at the anode surface. To some extent, the layer can prevent the attacks from the melt and oxygen.
