Abstract

Voltammograms with a bending point were found in the linear sweep voltammetry (LSV) of Pb2+/Pb0 redox systems in high temperature oxide melts. A model for the voltammogram was constructed in terms of a reversible redox reaction forming an insoluble deposit. The model involves a reaction of the deposit with an electrode metal, producing a metal solid solution and a liquid alloy. The whole shape of the voltammogram was reproduced by means of a computer simulation in terms of the model in which the diffusion process was solved using a difference equation of Fick's second law with appropriate boundary conditions. The present analysis of Mn+/M0 systems using the bending point will allow the extension of the LSV method to a wider variety of systems and be valuable for thermodynamic studies in high temperature melts.
