Abstract

Following the direct observation, by isothermal calorimetry studies, time-temperature-transformation (TTT) curves of the classical form for crystallization of ice from aqueous LiCl solutions, we have developed two step calorimetric studies which allow nucleation and growth contributions to the overall process to be separated. The position of the temperature of maximum nucleation rate is found, by the new measurements to lie 5 K higher in temperature than predicted by theoretical analysis of the TTT curves, though to have similar form. The results are to be regarded as preliminary in nature.
