N2 - The temperature-concentration dependences of the electrical conductivity and the activation energy for electrical conduction of glasses in the Na 2O-B2O3 and Na2O4-2PbO · B2O3 systems are studied. The investigation into the nature of the electrical conduction in these glasses reveals that the contribution from the electronic component (10-3%) of the conductivity is within the sensitivity of the Liang Wagner technique. A considerable alkali conductivity is observed upon introduction of more than ∼12 mol % Na2O. The true transport number of sodium η Na+ is as large as unity at [Na2O] ≒ 15 mol %. It is shown that the observed temperature-concentration dependences of the electrical and transport properties are governed by the ratio between the concentrations of polar and nonpolar structural-chemical units of the Na +[BO4/2]-, Na+[O-BO 2/2] ⇒ Na+[O-BO2/2], Pb 1/2 2+[BO4/2]-, Pb1/2 2+[BO2/2], and [BO3/2] types.
