Abstract

In this study a T-X phase diagram of K2S2O7-KHSO4 is calculated using the Landau-mean-field theory. By expanding the free energies of the solid phases of I, II and III in terms of the order parameters, the phase line equations are obtained among the following transitions: liquid-solid I, liquid-solid II, solid I-solid II, solid II solid III and liquid-solid III in K2S2O7-KHSO4.
