Abstract

The basic concepts of the delocalized-atom model have been shown to be applicable to low-melting-point sulfophosphate glasses and parameters of the model have been calculated. The parameters have been used to gain insight into the “atom delocalization” process in the glasses and assess their properties (viscosity, microhardness, glass transition temperature, and internal pressure). The results demonstrate that there is a linear correlation between the atom delocalization energy and glass transition temperature. The melt–glass transition is accompanied by the freezing of the atom delocalization process.
