The relation L ≅ t^½, between a length-scale L, characteristic of a system undergoing spinodal decomposition, and the time t, for a long time after the system has been quenched. The Lifshitz–Slyozov law applies below the spinodal curve to a system in which the order parameter is conserved. This law is in accord with light-scattering experiments on binary liquid mixtures. The Lifshitz–Slyozov law was put forward by the Soviet physicists I. M. Lifshitz and V. V. Slyozov in 1961.
