A relation between induction time and metastable zone width has been developed based on Classical Nucleation Theory, by which relation metastable zone width has been extrapolated from the induction time results and compared with experimental values. Influences of several thermodynamic and kinetic parameters on metastable zone width have been estimated.

A linear regression model is presented in this study to determine the pre-exponential factor and interfacial energy of the crystallized substance based on classical nucleation theory using the metastable zone width data. The nucleation event is assumed corresponding to a point at which the total number density of the nuclei has reached a fixed (but unknown) value. One equation is derived for any temperature-dependent functional form of the solubility. Another equation is derived for the van’t Hoff solubility expression. The pre-exponential factor and interfacial energy obtained from these two equations are found consistent for the studied systems, including glutamic acid, glycine, and 3-nito-1,2,4-triazol-5-one. The results obtained from these two equations are also compared with those obtained from the integral method and classical 3D nucleation theory approach.

Nucleation of salicylic acid in different solvents becomes gradually more difficult in the order: chloroform, ethyl acetate, acetonitrile, acetone, methanol and acetic acid. By comparing the results of metastable zone width and induction time experiments new insights are obtained.

The accumulated “nucleation potential” and “crystal density”, in the interpretations describing relation between metastable zone width and induction time, reach a critical value, respectively, at the nucleation in cooling crystallization.
