Qısa məlumat

The crystal structure and thermal properties of AgCuS compound were investigated at high temperature ranges. It was found that the crystal structure of these compounds has orthorhombic symmetry with Cmcm space group at the normal condition and room temperature. The phase transition to cubic symmetry with Fm3m space group is observed at T = 930 K temperature. The endoeffect was observed with a central peak at T = 938 K in the differential thermal analysis. The temperature dependence on heat capacity was obtained in the range of 300 K <= T <= 1300 K temperature. Thermodynamic parameters have been determined: enthalpy and heat capacity. The value of enthalpy was calculated according to the temperature of the phase transition.
