Another important point is the point at which the two coexisting phases coincide. This point is called the critical point. In a binary phase diagram, these are the lower and upper critical solution temperature of the phase curves. It is also the point where the binodal and spinodal coincide.

In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. One example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas cannot be liquefied by pressure alone. At the critical point, defined by a critical temperature Tc and …
