A phase diagram of the Ag2SO4 CaSO4 (Silver sulphate – Calcium Sulphate) binaries system using conductivity, XRD (XRay Diffraction Technique) and DTA (Differential Thermal Analysis) data is constructed. The eutectic reaction (liquid » aAg2SO4 CaSO4) is observed at 10 mole CaSO4 and 645°C. Room temperature solid solubility limit up to 5.27 mole of Ca 2 in Ag2SO4 is set using Xray powder diffraction and scanning electron microscopy results. All compositions beyond this limit are twophase mixtures below and above the transition temperature (≈ 416°C). The bulk conductivity, obtained following complex impedance spectroscopy, is found decreasing with increase in CaSO4 content. Amongst other binary compositions, the 80AgSO420CaSO4 gave improved sinterabilitypacking density.
