Abstract
The electrical properties of the solid electrolytes Ag7I4VO4-Al2O3 (0-40Â mol% Al2O3) are investigated. The electrical conductivity, dielectric constant and dielectric loss are increased by increasing the concentration of Al2O3; showing a maximum at 30Â mol% Al2O3. The conductivity is found to be increased by decreasing the particle size of Al2O3. The results are explained using the random resistor network model (RRN). This is due to the formation of a highly conducting interface layer along the matrix-particle interface. This layer is destroyed at concentrations higher than 30Â mol% Al2O3.
