Depolarised gas anodes for aluminium electrowinning G. M. HAARBERG1, E. KVALHEIM1, A. P. RATVIK1, S. J. XIAO1, T. MOKKELBOST2 1. Department of Materials Science and Engineering, Norwegian... carbon anodes are used in the electrowinning of aluminium by the Hall-Heroult process. Emissions of CO2 may be eliminated by introducing an inert oxygen evolving anode, which however will require......
and controlled pore sizes. Fig.3 Photos of porous Pb-0.8%Ag alloy with pore diameter of 1.60-2.00 mm: (a) Sample diagram; (b) Section diagram From Table 1 it can be seen that the porosity increases with the size of the filler particles. According to the principle of the negative pressure infiltration, the space occupied by the particles is the pore structure of porous lead alloy. Therefore......

. The activation mechanism of Mg-Al-Pb alloy is dissolving-reprecipitating and there is a synergistic effect between aluminium and lead: the precipitated lead oxides on the surface of the alloy can facilitate.... This indicates that aluminium has better depolarization effect than lead. Mg-6%Al-5%Pb alloy has the best electrochemical activation as well as the most negative stable potential(-1.400 V). So, it can......
