Abstract

The dependence of the fragility on the Grüneisen lattice parameter, which is a measure of the anharmonicity of lattice vibrations, is established for lead silicate and sodium borate glasses. An expression relating the fragility of glasses to the parameters of the Williams-Landell-Ferry equation is obtained. The calculation performed using this expression is in agreement with the results of the conventional determination of the fragility.
