The preparation of CeNi 5 by direct electrochemical reduction of mixed powders of cerium oxide (CeO 2) and nickel oxide (NiO) (atomic Ce/Ni ratio, 1:5) in a molten mixture of CaCl 2 and NaCl (mass CaCl 2/NaCl ratio, 7:3) at 820 °C has been studied. The influence of process parameters, such as sinter...
