内容記述 |
The electrical conductivities of glasses in the Ag2O-B2O3, Na2O-B2O3 and Ag2O-Na2O-B2O3 (Ag2O + Na2O = 27.4 mol% in average) systems have been determined over the temperature range from room temperature to about 400℃ using both d.c. and a.c. measurements. The temperature dependence of the electrical conductivities of the glasses could be described by the Rasch-Hinrichsen equation : σ = σ0exp (-ΔH/RT) The Ag2O-B2O3 glasses showed higher conductivity and lower activation energy for conduction than the Na2O-B2O3 glasses did. The mixed cation effect was observed in the Ag2O-Na2O-B2O3 system ; a minimum in the electrical conductivity and a maximum in the activation energy were found around the Ag/(Ag + Na) ratio of 1/5 on the property-composition curves. A minimum in the dielectric constant was also found. The magnitude of the mixed cation effect in the silver-containing system was, however, considerably smaller than that found in mixed-alkali glasses involving Li, Na, K or Cs ions. The electrical conductivity was much greater and the activation energy was smaller for the Ag2O-Na2O-B2O3 glasses of the composition range of Ag/(Ag + Na)>1/5, in which Ag+ ions are dominant current carries, than for the single cation Ag2O-B2O3 glasses of the same Ag2O content. This indicates that the mobility of Ag+ ions is increased on addition of Na+ ions in contrast with that of the alkali ions in mixed-alkali glasses which remains the same or is decreased on addition of alkali ions of the other type. Such behavior of the mobility of Ag+ ions was discussed by assuming the formation of Ag+ ion clusters which results in the shortening of the jump distances required for the migration of Ag+ ions. |
