Abstract: Phase separation may occur in a way that the growth is not in extent but in amplitude.Only in the unstable region such a procedure is thermodynamically feasible.In a phase diagram the unstable region is defined by the spinodal.When a system has crossed this locus, phase separation occurs spontaneously without the presence of a nucleation step.This process is known as spinodal decomposition and commonly results to a high interconnectivity of the two phases.The Cahn-Hilliard equation describes the kinetics of the process.In this note both processes (nucleation and spinodal) are depicted schematically.
