Correlation Between Thermodynamic and Kinetic Fragilities in Non- Polymeric Glass-Forming Liquids (Preprint)

摘要

A theoretical relationship between reduced excess heat capacity of super-cooled liquid at the glass transition temperature, fragility index m and reduced glass transition temperature, was derived from fragile non-polymeric glass-forming liquids under the assumptions that the fragile behavior of these liquids is described by the Vogel-Fulcher-Tammann (VFT) equation, the excess heat capacity of liquid is a hyperbolic function of the absolute temperature, and the VFT temperature is equal to the Kauzmann temperature.
