Thermal behavior of the above glass has been studied by the methods of dilatometry and DSC. The study of electrical characteristics of glass showed that their electrical conductivity is in the range 8 × 10−9−3 × 10−8 Sm/cm at 25°C, 5 × 10−4−10−3 siemens/cm at 300°C. The obtained values of the electrical conductivity are on the level of the best values known for sodium glassy solid electrolytes. It was found that the introduction of phosphorus oxide leads to a decrease in the conductivity of the glass. Доп.точки доступа: Vlasova, S. G.; Reznitskikh, O. G.
