Abstract

The glasses of the formula 10ZnO.xNa₂O.(90-x)B₂O₃, 25ZnO.xNa₂O.(75-x)B₂O_, xZnO.10Na₂O.(90-x)B₂O₃, and xZnO.25Na₂O.(75-x)B₂O₃ were prepared using melt quenching method. The prepared glasses were characterized using FTIR, Dc conductivity, density and molar volume techniques. The Dc conductivity results indicate that the conduction in studied glasses strongly depends on Na₂O content/or N (number of Na⁺ ions per cm³). The linear dependence of conductivity on mobility of Na⁺ ions, reveals that mobility is a basic parameter that determines conductivity and activation energy in all studied glasses. The structural analysis and the conduction results indicate that the mobility is dominated by N the number of Na⁺ ions per cm³, which depends on the concentration (x) of Na₂O and the free volume. Regardless of composition, Dc conductivity, mobility, and activation energy showed a unique dependence on N number of Na⁺ ions per unit volume in all studied glasses.

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
