Limiting current densities of silver deposition in AlCl3-NaCl-AgCl or LiCl-KCl-AgCl melts, and change in the equilibrium potential of silver with AlCl3 concentration were measured to consider a large potential difference in the two melts. Diffusion rate of silver species in AlCl3-NaCl-AgCl melt was concluded to be much slower than that in LiCl-KCl-AgCl melt. The formation of a silver complex in AlCl3-NaCl-AgCl melt was suggested. The equation, Ag + AlCl4− = AgAlCl4 + e or Ag + 2 A1Cl4− = Ag(AlCl4)2− + e., might be a possible electrochemical reaction of silver in the melt.
