Abstract

The cooling rate dependence of the homogeneous nucleation temperature, T_h, has been determined for several compositions in the system LiCl/H₂O. This cooling rate dependence was found to be small except at concentrations close to the edge of the glass-forming range. An explanation of the often observed termination of the T_h curve at ∼T_g + 22 K is developed. Little prospect is found of improving the vitrification range of cryoprotectant solutions by the imposition of high quench rates.
