Аннотация:The heat capacity of Ga2Se3 is measured from 14 to 320 K by adiabatic calorimetry. The smoothed heat capacity data are used to evaluate temperature-dependent thermodynamic functions (entropy, enthalpy increment, and reduced Gibbs energy) of gallium selenide. Under standard conditions, the thermodynamic properties of Ga2Se3 are C-p(0) (298.15 K) = 120.8 +/- 0.2 J/(K mol), S-0(298.15 K) = 180.4 +/- 0.4 J/(K mol), H-0(298.15 K) - H-0(0) = 25.32 +/- 0.05 kJ/mol, and Phi(0)(298.15 K) = 95.52 +/- 0.19 J/(K mol). The Debye characteristic temperature of Ga2Se3 evaluated from heat capacity data is 340 +/- 10 K.
