The dependence of the induction period of crystallization on the supercooling was examined for the ZnCl2-ethylene glycol system at mole fractions of the salt from 0 to 0.07, and treated in terms of the TTT (Time-Temperature-Transformation) diagram. The critical induction period of crystallization increases substantially on the addition of ZnCl2 to ethylene glycol. The thermal stability of supercooled liquids is discussed in terms of the shape and position of the TTT curves.
