RATE OF ENTROPY LOSS WITH TEMPERATURE IN LIQUIDS AND ITS RELATION TO GLASS FORMING ABILITY OF MATERIALS.

Abstract

The present paper deals with the evaluation of the ideal glass transition temperature from a knowledge of the ratio of the heat capacity and entropy differences between the liquid and solid phases at the equilibrium melting temperature of a material. This ratio is known to be a measure of the rate of entropy loss with temperature for the liquid phase. It has been shown that a correlation exists between the critical cooling rate for glass formation and the magnitude of the ratio of the heat capacity and the entropy of fusion.
