Before revision: In 1921, Vegard discovered that the lattice parameter of a solid solution of two constituents is approximately a weighted mean of the two constituents' lattice parameters at the same temperature: e.g., in the case of a mixed oxide of uranium and plutonium as used in the fabrication of MOX nuclear fuel: Vegard's law assumes that both components A and B in their pure form (i.e.
