Title: The existence of the spinodal and its relation to spinodal decomposition
Abstract: The most well-known theory of spinodal decomposition depends on the existence of a free energy versus composition curve for a binary solution which exhibits a maximum within the region of the miscibility gap of its phase diagram. Such a maximum cannot exist unless special constraints are applied to the thermodynamic system. The role of these constraints, their clear specification, and the possible confusion associated with the use of mean field models are discussed. Attention is drawn to the fact that the conventional criterion of stability against decomposition is only true in an asymptotic limit.
