Abstract The cyclic vltammetry, electrode potential--time curve after potentiostatic elec-trolysis, potential step method and X--ray diffraction were used to study the electrode process ofPr(III) reduced on Ni electrode in molten NaCl--KCl--PrCl_3 and to determine the diffusioncoefficient of Pr into its alloy phase. The Pr-Ni alloys are formed before the deposition of me-tallic Pr. The PrNi_5 is formed on electrode first and then the intermetallic compounds containedmore Pr are formed in sequence. The standard free energy of formation for PrNi_5 has also beendetermined.
