Abstract The ionic conductivities and phase diagrams of AgI-Ag2SO4, AgCl-Ag2SO4 and AgBr-Ag2SO4 systems have been studied with the help of electrical conductivity, transport number, DTA and X-ray studies. In the AgI-Ag2SO4 system, the solid solution of α-AgI with Ag2SO4 was quenched to room temperature to have high ionic conductivity of 5·0×10−2 (ohm. cm)−1 at room temperature and 1·3×10−3 (ohm. cm)−1 at −78°C. The quenched solid solution was stable at −20°C, but gradually decomposed toβ-AgI andβ-Ag2SO4 at room temperature. The transport number of silver ion in this solid solution was about 1·0. In the AgCl-Ag2SO4 and AgBr-Ag2SO4 systems, the electrical conductivity was of the order of 10−4 to 10−6 (ohm. cm)−1 at room temperature.
