A new quaternary superionic conducting AgIAg2O(SeO3 + MoO3) glasses with different compositions of the dopant salt AgI were prepared by rapid melt quenching. The compounds were characterised by X-ray diffraction, scanning electron microscopy and infrared spectroscopy, and glass-forming compounds were identified. The frequency dependence of electrical conductivity, σ, complex permittivity, ϵ ∗ , and electrical modulus, M ∗ , were studied for various compositions of the dopant salt AgI at different temperatures. At room temperature, 293 K, the highest conductivity, σ = 3.12 × 10−2 S/cm is obtained for the glass with 60% AgI. The ionic conductivity σ and the complex permittivity ϵ ∗ is described in terms of ion diffusion and polarisation. The composition and temperature dependence of the electric modulus M ∗ is studied and the results are reported.
