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.

T-X phase diagram of (NH4)(2)SO4/H2O Yurtseven, Hasan Hamit; Sen, S.; Salihoglu, S. (2007-04-01) Using the mean field theory, we obtain the phase line equations for the liquid-solid I, liquid-solid II and solid I-solid II transitions in (NH4)(2)SO4/H2O. We fit our phase line equations to the experimental T-X phase diagram of this system. Thus, we are able to obtain the temperature and concentration dependencies of the order parameters and the free energies in this system.
T-P phase diagram of ammonia solid phases I, II and III Enginer, Y; Salihoglu, S; Yurtseven, Hasan Hamit (2002-01-01) In this study, using the mean field theory, we obtain temperature versus pressure phase diagram for the liquid and solid phases I, II, and III of ammonia. We fit, our phase line equations to the experimentally observed data. There exists good agreement between the theoretical and experimental phase lines.
P-T phase diagram at various concentrations for the NH4BrxCl1-x system Salihoglu, S; Tari, O; Yurtseven, Hasan Hamit (2001-08-01) We calculate here using the mean field theory, the phase-line equations for the gamma-beta, delta-beta and delta-gamma phase transitions in the NH4BrxCl1-x system. We fit our P-T phase diagrams calculated at various concentrations to the experimental data for this crystalline system. Our results show that there is a good agreement between our calculated and experimentally observed phase diagrams for the NH4BrxCl1-x system.
T-P phase diagram for ice Yurtseven, Hasan Hamit; Salihoglu, S.; Sen, S. (2008-05-01) In this study we obtain a T-P phase diagram of ice using the mean-field theory. We fit our calculated phase line equations to the experimental T-P 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 ice. Some thermodynamic functions are calculated using the free energy for the transitions studied here.
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.
