and chronopotentiometry were used to investigate the reduction mechanism of the electrochemical deposition of Sc3+ to Sc on Ag electrode in LiF-NaF system at 1043 K. Experimental results indicate that the electroreduction of Sc3+ to Sc is a reversible process with simple 3-electron transfer in one step controlled by diffusion. Key words:scandium; reduction mechanism; cyclic voltammetry; chronopotentiometry; rare......

April 2011; accepted 23 June 2011 Abstract: Cyclic voltammetry and chronopotentiometry were used to study the reaction mechanism of Pb(II) and the co-deposition of Pb, Mg and Li on molybdenum electrodes... and chronopotentiometry indicated that the underpotential deposition of lithium on pre-deposited Pb leads to the formation of a liquid Li-Pb alloy, and the Mg-Li-Pb alloys are formed after the addition of MgCl2. X-ray......
