− The electrochemical behavior of Nd 2 O 3 -La 2 O 3 -NiO mixed oxide including rare earth resources has been studied to synthesize La 0.5 Nd 0.5 Ni 5 alloy in a LiCl molten salt. The Nd 2 O 3 -La 2 O 3 -NiO mixed oxide was converted to NiNd 2 O 4 (spinel) and LaNiO 3 (perovskite) structures at a sintering temperature of 1100 C. The spinel and perovskite structures led a speed-up in the electrolytic reduction of the mixed oxide. Various reaction intermediates such as Ni, NiLa 2 O 4 were observed during the electrochemical reduction by XRD analysis. A possible reaction route to La 0.5 Nd 0.5 Ni 5 in the LiCl molten salt was proposed based on the analysis result.
