The results indicate that anodic overvoltage was reduced by the rare earth additive which increased the electro-catalytic activities of the carbon anodes. In the range of industrial current densities (0.5 to 1.0 A/cm2), the anodic overvoltage reduced by 0.2 to 0.34 V. The estimated energy saving will be 600 to 1100 kWh/t Al., The results indicate that anodic overvoltage was reduced by the rare earth additive which increased the electro-catalytic activities of the carbon anodes.
