Abstract
The glass forming region for AgI, Ag 2O and V 2O 5 ternary system was determined. On the basis of the glass forming region, the glass transition temperature, density, ionic conductivity and Raman scattering experiments were performed for nAgI–3Ag 2O–2V 2O 5 ( n=0–10) glasses. The glass transition temperature and the density varies linearly with AgI concentration. On the other hand, the activation energy for ionic conductivity and the electric modulus indicate different composition dependence at about 40 mol.% of AgI. It is verified that the network structure is essentially the same below and above this composition by Raman scattering experiment. The formation of AgI partial structure in higher AgI-doped glasses and its relation to the cluster model is discussed in terms of both the present experimental results and previous diffraction experiments.
