In this study we obtain a T-X phase diagram of Na2S2O7-NaHSO4 using the mean field theory. We fit our calculated phase line equation to the experimental T-X phase diagram. By choosing appropriately the coefficients in the free energy expansions, our calculated phase diagram agrees well with the experimentally observed phase diagram of Na2S2O7-NaHSO4.

Calculation of the phase diagram using the Landau-mean-field theory for K2S2O7-KHSO4 Sen, S.; Yurtseven, Hasan Hamit (Elsevier BV, 2009-03-15) 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.
P-T phase diagram for NH4F Salihoglu, S; Yurtseven, Hasan Hamit; Enginer, Y (2002-04-01) In this study we obtain a P-T phase diagram of NH4F using the mean-field theory. We fit our calculated phase line equations to the experimental P-T phase diagram. By choosing appropriately the coefficients in the free-energy expansions. our calculated phase diagram agrees well with the experimentally observed phase diagram of NH4F.

A phase diagram for ammonium halides Yurtseven, Hasan Hamit; Tublek, A (Informa UK Limited, 1995-01-01) In this study we have developed a mean field model to obtain the phase diagrams for NH4Cl and NH4Br. The phase diagrams obtained from our macroscopic theory are in good agreement with those obtained experimentally.
Calculation of a generalised smectic–hexatic phase diagram in liquid crystals Yurtseven, Hasan Hamit (Informa UK Limited, 2012-5) This study gives a generalised smectic-hexatic phase diagram calculated by the Landau mean field theory. Our calculated phase line equations are fitted to the experimental phase lines, which represent first-order transition for the liquid crystals studied here. The temperature-and concentration-dependent phase lines calculated in this study describe the observed T-X phase diagram for the smectic-hexatic transitions. This indicates that the method of calculating the phase line equations from the mean field t...
Calculation of a phase diagram for the ice II-V-VItransitions Tari, O; Yurtseven, Hasan Hamit; Salihoglu, S (2000-12-01) In this study we calculate the P - T phase diagram of ice II - V - VI using a mean field model. Our calculated phase line equations are fitted to the experimental data from the literature. There is a very good agreement between our calculated and experimentally observed P - T phase diagram of ice II - V - VI.
