| Abstract: | The thermodynamic investigation of the system TiSe2-TiSe1.80 was carried out by the static method of vapor pressure measurements using the quartz membrane-zero manometers in the temperature range from 713 to 1395 K. The analysis of the p Se-T-x dependences obtained showed that titanium diselenide formed a continuous solid solution. The enthalpies and entropies of dissociation processes of TiSe x were derived from the experimental data. The standard enthalpies of formation, the absolute entropies, and the free Gibbs energies of formation of selenides belonging to the homogeneity region of TiSe2 were estimated using literature data. The obtained set of thermodynamic characteristics may be used for the calculation of phase equilibria and for thermodynamic modeling in the system Ti-Se. |
