of thermodynamic property for this substance is necessary. In this study, the low-temperature heat capacities of this compound over the temperature range from 78 to 350 K were measured by an automated adiabatic calorimeter. The thermodynamic functions
the study in detail. In this article, we report the phase diagram study, thermal study of the pure compounds and the eutectics such as heat of fusion, Jackson’s roughness parameter, excess thermodynamic functions, and microstructural study. However
, calculation of standard ( p ° = 0.1 MPa) thermodynamic functions: , H °( T ) − H °(0), S °( T ), and G °( T ) − H °(0) of crystalline Ph 4 SbONCPhMe from T → 0 K to 350 K using the experimental data, determination of combustion energy of the compound
are important basic thermodynamic function of substances. Based on the polynomials of molar heat capacity and the thermodynamic relationships, the [ H T − H 298.15 ] and [ S T − S 298.15 ] of DPFEB are calculated over the experimental temperature
–380 K. The thermodynamic properties including molar enthalpy and entropy of phase transition were determined based on the heat capacity measurement. Further more, the thermodynamic functions such as [ ] and [ ] were calculated from the heat capacity

]. In this study results of experimental studying of temperature dependence of a heat capacity of crystal compound Ba 0.5 Zr 2 (PO 4 ) 3 over the temperature range 6–612 K are presented, the standard thermodynamic functions C p o ( T ), H °( T ) − H
). The equations describing the excess solution thermodynamic functions can be presented as [ 24 , 27 , 28 ]: (21) (22) (23) (24) (25) (26) (27) (28) where ϕ and γ are osmotic and activity coefficients, respectively; and are the partial molar
phenomenon remain in quest. With a view to ascertain the behaviour of eutectic phenomenon in the phase equilibria, excess thermodynamic functions are thought to be the best tool to reveal the molecular interactions between the binary condensed phases
