ABSTRACT
The electrochemical behavior of nickel in the K2WO4–Na2WO4 (1 : 1) – WO3 (35 mol. %) and K2WO4–Na2WO4 (1 : 1) – WO3 (50 mol. %) polytungstate melts was studied by the cyclic voltammetry. Based on a comparison of the obtained cyclic voltammograms with the data of SEM, EDS and XRD conclusions were drawn about the sequence of processes proceeding on the nickel substrate. Equations of the electrolysis products formation are proposed.
