The aim of this program was to develop the techniques and understanding necessary for the growth of films or single crystals of a variety of materials by molten salt electrocrystallization. The conditions for stable growth of materials by this technique have been explored both theoretically and experimentally. The theoretical studies have shown the importance of a high solute concentration, the potential gradient at the crystal-solution interface and of a material parameter which we have termed the growth rate constant. The current density, which determines the rate of deposition, is also a crucial parameter in many experiments and a value in the range 10-50 milli-Angstrom/sq cm must not be exceeded if stable growth is to occur.
