This is largely because the distribution of the alloying elements in the compounded precursor is uniform at the atomic level within a short distance. Thus, once the oxygen atoms are removed at appropriate potentials, these closely arranged alloying atoms can react quickly to form the desired alloys or intermetallics. 54, 55 La2O3 is a hygroscopic oxide and can react spontaneously with molten CaCl2, which challenges the usual method of preparing the oxide precursor, and maintain its integrity in the molten salt during electrolysis.
