What Is Spinodal Nucleation?

Spinodal decomposition occurs when one thermodynamic phase spontaneously (i.e., without nucleation) separates into two phases. ... When there is a nucleation barrier to the formation of a second phase, the system takes time to overcome that barrier.

What is spinodal?

In thermodynamics, the spinodal is the limit of stability of a solution, denoting the boundary of absolute instability of a solution to decomposition into multiple phases. ... Outside of the curve, the solution will be at least metastable with respect to fluctuations.

What is a spinodal curve?

Spinodal Curve: A curve that separates a metastable region from an unstable region in the coexistence region of a binary mixture.
