摘要：
The composition of the diffusion zone formed during the interaction between 20Na2O · 80SiO2 glass and molten silver, rubidium, cesium, and thallium nitrates with and without imposition of a constant electric field was determined using X-ray microanalysis. The interdiffusion coefficients and values of electrical mobility were calculated, and the parameters of temperature dependence were determined. The electrical mobility was almost independent of the size and chemical nature of a cation and was determined by the mobility of the cation included into the initial glass.
