On the estimation of surface entropy factor, interfacial tension, dissolution enthalpy and metastable zone-width for substances crystallizing from solution

Abstract

Surface entropy factors, interfacial tensions, dissolution enthalpies and metastable zone-widths for substances crystallizing from solutions are estimated and compared with literature values. It is shown that the expression relating surface entropy factor with heat of melting, melting point and crystal solubility predicts reliable values of surface entropy factors and interfacial tensions. In combination with the equation for critical supersaturation given by the classical nucleation theory, the same equation also predicts satisfactory values of metastable zone-widths for compounds growing from solutions.
