The Influence of the Parameters of Electrolysis Carried Out with Periodic Reversal Current (PRC) on the Morphology of Silver Obtained Via Silver Chloride Cathodic Reduction
The aim of this study was to determine the possibility to obtain compact silver deposit during cathodic reduction of AgCl with the use of periodic reversal current (PRC).
The influence of the electrolysis parameters (current intensity I = 0.4-1.6 A, the ratio of working to reversal periods tw/trv = 100/10; 100/20; 100/30) on the silver morphology (size and shape of Ag grains).
Under the applied electrolysis conditions powder deposits were obtained, but at I = 0.4 A and tw/trv = 100/10 a more compact deposit was produced. Cathode efficiencies of the processes were low and ranged from approx. 52% up to 85%.
