The thermodynamic characteristics of lanthanum deposition into a solid nickel cathode from molten electrolytes were investigated using polarization curves with a galvanostatic pulse technique. The experiments were performed under argon using a lead reference electrode and encased auxiliary electrode of spectroscopically pure graphite. The lanthanum deposition potential required to calculate Gibbs energy changes was determined experimentally during electrolysis of the melt with a molybdenum cathode and it was found that thermodynamic characteristics of solid phases can be determined directly from polarization measurement.
