Predicting the Thermodynamic Ideal Glass Transition Temperature in Glass-Forming Liquids.

The Kauzmann temperature is a lower limit of glass transition temperature, and is known as the ideal thermodynamic glass transition temperature. A supercooled liquid will condense into glass before . Studying the ideal glass transition temperature is beneficial to understanding the essence of glass transition in glass-forming liquids. The Kauzmann temperature values are predicted in 38 kinds of glass-forming liquids. In order to acquire the accurate predicted by using a new deduced equation, we obtained the best fitting parameters of the deduced equation with the high coefficient of determination ( = 0.966). In addition, the coefficients of two reported relations are replaced by the best fitting parameters to obtain the accurate predicted , which makes the values increase from 0.685 and 0.861 to 0.970 and 0.969, respectively. Three relations with the best fitting parameters are applied to obtain the accurate predicted values.
