Crystallization

In the absence of any solid particles the curve FG represents the limit at which nucleus formation begins spontaneously and, consequently crystallization starts – this line (FG) is called the super solubility curve. According to Mier''s theory at any point between C and D point nuclei cannot form and crystallization cannot occur.
