Anodic dissolution of Pb-Sb alloys in an equimolar mixture of potassium and lead chlorides

The effect of temperature and antimony concentration on the anodic dissolution of Pb-Sb alloys in an equimolar KCl-PbCl 2 melt is investigated. It is shown that, up to the specific values of the current densities, the main process is lead dissolution, which starts at near-equilibrium potentials. The theoretical anode polarization curve for the dissolution of Pb-Sb alloys is calculated. It is established that the limiting stage is the mass transfer from the alloy side.
