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-X-Br phase diagram for the NH4BrxCl1-x system Tari, O; Yurtseven, Hasan Hamit; Salihoglu, S (Informa UK Limited, 2000-01-01) In this study using a mean field model we calculate the phase line equations for the beta-delta, beta-gamma and gamma-delta phase transitions in the NH4BrxCl1-x system. We then fit our phase line equations to the experimentally observed T-X-Br phase diagram for this system. Our calculated phase diagram agrees well with the observed one for the NH4BrxCl1-x system.
T-P Phase Diagram of Nitrogen at High Pressures Algul, G.; Enginer, Y.; Yurtseven, Hasan Hamit (2018-05-01) By employing a mean field model, calculation of the T-P phase diagram of molecular nitrogen is performed at high pressures up to 200 GPa. Experimental data from the literature are used to fit a quadratic function in T and P, describing the phase line equations which have been derived using the mean field model studied here for N-2, and the fitted parameters are determined. Our model study gives that the observed T-P phase diagram can be described satisfactorily for the first-order transitions between the ph...
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.
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.
