Abstract:
Pb-Sn-Al (PSA) laminated composite electrode materials were prepared by means of vacuum hot pressing (VHP), through introducing a medium Sn for solving the immiscibility of Pb and Al. Compared to traditional Pb-(1.0%)Ag alloy electrode, zinc eletrodeposition experiments showed that the cell voltage was reduced by at least 120 mv, the polarization potential of electrode was decreased by 13.2%, the current efficiency was higher 1.3% and the surface morphology of cathode zinc was better and smoother as well as zinc crystals smaller and more dense, while the experiment of the resistance test also showed that the resistance was reduced by at least 50%, therefore, Pb-Sn-Al (PSA) laminated composite electrode materials have lower cell voltage, as well as excellent conductivity, which would have good prospect in development and application in zinc hydrometallurgical industry in the future.
