Abstract/Summary Carbon dioxide generated at the electrolytic face of operating anodes permeates the anode structure and reacts to form carbon monoxide. This gasification increases anode porosity and generates a reaction porosity profile, with internal attack decreasing to the limit of C02 permeation into the anode. Mercury porosimetry has been used to establish the mechanism of reaction porosity generation and to define an active pore size range within the anode structure. In all anodes studied, porosity generated by sub-surface oxidation was largely in the sub-micrometre region of the anode pore volume distribution. A model of the anode structure is proposed to account for reaction in these fine pores.
