N2 - The temperature-concentration dependence of the electrical conductivity of glasses in the Na2SO4-NaPO3 and Na 2O-P2O5 systems has been investigated. Based on the obtained experimental data (IR spectra, density, microhardness, sound velocity, and paper chromatography), it has been demonstrated that SO 4 2- ions form terminal groups through the incorporation into polyphosphate fragments of the structure of glasses in the Na 2SO4-NaPO3 system.
