Thermodynamic properties of pentalead tris(vanadate) chloride
چکیده انگلیسی

In the present work the temperature dependences of pentalead tris(vanadate) chloride heat capacity have been measured for the first time in the range from 7 to 350 K. The experimental data were used to calculate standard thermodynamic functions, namely the heat capacity Cp ° (T), enthalpy H°(T) − H°(0), entropy S°(T) − S°(0) and Gibbs function G°(T) − H°(0), for the range from T → 0 to 350 K. The differential scanning calorimetry in temperature interval 298–1473 K was applied to measure temperatures of phase transition and melting of compound under study. The high-temperature X-ray diffraction in range 298–1073 K was used for the determining thermal expansion coefficients.
