Abstract

Glass transition temperatures (T_g) of the system LiCl-DMSO-H₂O have been measured. A small addition of DMSO to the binary aqueous system removes its unusual variation of T_g with salt concentration. The concentration dependence of T_g of the ternary system at a constant composition of the mixed solvent can be described by a linear equation. The variation in T_g with the mixed solvent composition at constant LiCl concentration follows a complicated pattern which cannot be described by commonly used relations. The boundaries of glass-forming region are discussed in terms of the effect of a change in solution composition on the induction period of equilibrium solid phase nucleation.
