INVESTIGATION OF THE CATHODE WEAR MECHANISM IN A LABORATORY TEST CELL

摘要: Cathode wear has become one of the major challenges for life time high amperage aluminum reduction cells due to use graphitized cathodes. The fundamentals cathode are still a matter debate, and laboratory procedure testing materials is desired. Here, we present electrolysis cell, which been designed tests industrial materials. formation transport carbide have considered be an important factor wear, test cell was in such way that exposed directly electrolyte. Aluminum formed at may dissolve into Here study commercial density graphitic material, where influence surface morphology, diffusion hydrodynamics electrolyte, focus. penetration electrolyte were investigated by optical electron microscopy. current density, electrode discussed relation experimental results.
