The crystal structure and thermal properties of the Ca0.5In1.5Se3 compound have been investigated. Structural studies were performed by X-ray diffraction at room temperature. The crystal structure of this compound was found to correspond to the hexagonal symmetry of the space group P6₁. Thermal properties were studied using a differential scanning calorimetry (DSC). It was found in the temperature range 25∘C ≤ T ≤ 950∘C that thermal effects occur at temperatures T1 = 102∘C and T2 = 848∘C. The thermodynamic parameters of these effects are calculated.
