N2 - The nature of current carriers is revealed and the concentration dependence of the true transport numbers of chlorine ions η is studied by the Tubandt method in glasses of the PbCl2-2PbO · SiO2 system. It is demonstrated that, in glasses containing up to ∼20 mol % PbCl2, the electricity transport occurs through protons and chlorine ions. At [PbCl2] ≥ 20 mol %, the electric current is carried primarily by the chlorine ions. The known crystalline compounds in the PbO-PbCl2 system are synthesized, and the temperature dependences of their electric conductivity are investigated for the first time. It is found that the introduction of PbCl2 into PbO is accompanied, first, by an increase in the electric conductivity (to a PbCl2 mole fraction of ∼0.5), and, then (when PbCl2 single crystals are formed), by its decrease. The temperature-concentration dependence of the electric conductivity for glasses in the PbCl2-2PbO · SiO2 system is interpreted in terms of structural-chemical microinhomogeneity of the glass structure due to the selective interaction of components during the glass synthesis.
