Electrodeposition of metals (such as Ag, Bi, Cd, Co, Cu, Ni, Pb, Pd, Pt, and Zn) from nonaqueous DMF solutions saturated with the corresponding metal salts was investigated under steady-state current with no agitation.
Crystals having regular dendritic structure were formed in cases of Co, Ni, Pb, and Zn under current density of 10-64mAmp/cm2. Whereas, less crystalline or amorphous deposits were obtained in case of Pt.
The deposits of Bi, Cd, Cu, and Pd were grown up into dendritic or mossy structure, according to the current density.
The growth of the dendritic structure was controlled by the following factors:
1. Current density and exchange current density
2. Ion concentration
3. Ionic conductivity
The leading factors for promoting the growth of dendritic structure in D.M.F. solutions were low exchange current density and low ionic conductivity.
