Curve defining the region of composition and temperature for a binary mixture across which a transition occurs from conditions where single-phase mixtures are @M03872@ to conditions where single-phase mixtures are @U06569@ and undergo @P04534@ by @S05869@.
Notes:
- The spinodal curve for a binary mixture is defined as the geometrical locus of all states with \[\left ( \frac{\delta^{2}\Delta _{\text{mix}}G}{\delta\phi ^{2}} \right)_{T,p} = 0\].
- In the @U06569@ region bounded by the spinodal curve, @PT07286@ separation is spontaneous, i.e., no nucleation step is required to initiate the separation process.
