Preferred Label : spinodal;
IUPAC definition : Curve defining the region of composition and temperature for a binary mixture across
which a transition occurs from conditions where single-phase mixtures are metastable
to conditions where single-phase mixtures are unstable and undergo phase separation
by spinodal decomposition.;
Scope note : in the unstable region bounded by the spinodal curve, phase domain separation is spontaneous,
i.e., no nucleation step is required to initiate the separation process.; the spinodal curve for a binary mixture is defined as the geometrical locus of all
states with ¿2 dmixg t p 0 .;
