Abstract

The regularities of the initial stages of growth of silver nano- and microcrystals during electrodeposition from the AgNO3-KNO3-NaNO3 melt with an excess background electrolyte are studied. A model for the electrocrystallization process is proposed. Experimental and theoretical time dependences of the overpotential (supersaturation) and the crystal size are obtained. The applicability of this model is discussed. The main electrodeposition parameters are found to be the specific capacity of a double electrical layer, the equilibrium concentration of single adatoms at the electrode, and the diffusion coefficient of depositing ions in the melt.
