The phase diagram of the catalytically important K2S2O7-KHSO4 molten salt solvent system has been investigated by electrochemical, thermal and spectroscopic methods.It is of the simple eutectic type with a temperature of fusion of 205C for the eutectic composition, X(KHSO4)= 0.94. The conductivities of the solid and molten K2S2O7-KHSO4 system were measured at 13 different compositions in the whole composition range, X(KHSO4)= 0-1. The conductivity of the molten mixtures were fitted to polynomia of the second degree.The results indicated delocalization of the conducting ions compared to the pure molten components.
