DETERMINATION OF THERMODYNAMIC FUNCTIONS OF PHASE TRANSITION OF Cu8SiSe6 COMPOUND BY THE DSC METHOD
The ternary compound Cu8SiSe6 was studied by differential scanning calorimetry (DSC). Based on the data of DSC curves for two samples with different masses, the temperature and enthalpy of the phase transition from the low-temperature orthorhombic modification to the high-temperature cubic modification were determined. Using the Gibbs-Helmholtz equation, the entropy of the phase transition of the studied compound was also calculated.
