N2 - The glass formation region in the Na2Se-P2Se 5 system and the temperature-concentration dependences of the electrical conductivity of glasses have been investigated over a wide range of temperatures. The densities and glass transition temperatures T g of glasses have been determined. A comparison of the electrical conductivity of glasses in the Na2Se-P2Se5 and Na 2O-P2O5 systems has demonstrated that the conductivity of selenium-containing glasses (at 25°C) is approximately three orders of magnitude higher than the electrical conductivity of oxide glasses. The assumption has been made that an increase in the electrical conductivity of glasses with selenium is caused by the increase in the degree of dissociation of Na+[Se-PSe3/2] polar structural chemical units and the higher mobility of sodium ions in the oxygen-free matrix.
