摘要：
The temperature-concentration dependence of the electrical conductivity of glasses in the NaPO3-NaF system has been investigated. The regularities revealed are interpreted from the standpoint of the structural microinhomogeneity of glasses, which is due to the formation of polar structural units of the Na+[O-POO2/2], Na-2(+)[O-2(-) POO1/2], Na+[F-POO2/2], and Na+F- types. It is shown that the concentration dependence of the electrical conductivity is governed by the ratio between the concentrations of these structural units.
