This system was investigated by using differential scanning calorimetry, microthermal, X-ray diffraction and conductivity measurements. It was found that the phase transitions which occurred upon quenching the melt were reproducible and reflected the formation of 2 types of glass. The system exhibited 2 eutectic temperatures, at 275 and 360C, and it was suggested that the components had reacted chemically to give a new compound. On the basis of estimates of the eutectic compositions, it was concluded that the new compound was AgI·2AgVO3. The conductivity at room temperature depended upon the composition and upon the preparation method. A solid with 65mol%AgI, obtained by quenching the melt, was found to exhibit a maximum conductivity of 0.022S/cm at 294K. By using the same preparation method, superionic conductivities could be obtained in compositions ranging from 40 to 85mol%AgI.
