The electrochemical features, electrode capacity and corrosion stability, of silver alloys with Tl, Pb, P,Sb, Ge and In have been investigated. Compared to silver some silver alloys showed improved silver oxide formation and conductivity. The best effects, i.e., dramatic increases of 150% for formation of oxide, were obtained with small amounts of alloying component: 0.44% Tl or 0.44% Pb. Based on obtained results, those effects could be explained in terms of increase of real electrode surface as a consequence of ingredients oxidation, preceding the silver oxidation.
