Predicting the Thermodynamic Ideal Glass Transition Temperature in Glass-Forming Liquids
The Kauzmann temperature T(K) 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 T(K). Studying the ideal glass transition temperature is beneficial to understanding the essence...

description | The Kauzmann temperature T(K) 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 T(K). Studying the ideal glass transition temperature is beneficial to understanding the essence of glass transition in glass-forming liquids. The Kauzmann temperature T(K) values are predicted in 38 kinds of glass-forming liquids. In order to acquire the accurate predicted T(K) by using a new deduced equation, we obtained the best fitting parameters of the deduced equation with the high coefficient of determination (R(2) = 0.966). In addition, the coefficients of two reported relations are replaced by the best fitting parameters to obtain the accurate predicted T(K), which makes the R(2) 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 T(K) values. |
