We propose a new model for dielectric relaxation in mixed-alkali silicate glasses. The main features of the model are connected with the presence of three different microscopic processes contributing to the dielectric function. These processes are associated both with alkali-alkali static and dynamic correlations. The new model provides the fundamentals of a recently proposed empirical equation for ionic conductivity in mixed-alkali silicate glasses.

Abstract
We propose a new model for dielectric relaxation in mixed-alkali silicate glasses. The main features of the model are connected with the presence of three different microscopic processes contributing to the dielectric function. These processes are associated both with alkali-alkali static and dynamic correlations. The new model provides the fundamentals of a recently proposed empirical equation for ionic conductivity in mixed-alkali silicate glasses.File in questo prodotto:
