Cadmium arsenides, particularly Cd₃As₂, have attracted considerable attention for their potential in advanced electronics, spintronics, and optoelectronics applications, owing to their exceptional charge transport properties and unique Dirac semimetal behavior. The combination of tunable bandgap and high carrier mobility makes them promising candidates for next-generation devices, including high-speed electronics and infrared photodetectors. Considering the inconsistent results in the available literature and the contemporary relevance of the research objects, a thermodynamic study of the α-Cd3As2 and CdAs2 compounds in the 300–450 K temperatures range by low-temperature electromotive force method has been carried out in the present work. Measurements were performed using equilibrium samples taken from the CdAs2 + As and α-Cd3As2 + CdAs2 two-phase regions of the Cd-As system. The phase compositions of all samples were controlled using the powder X-ray diffraction method. The partial molar functions of cadmium in alloys, as well as the standard thermodynamic functions of the formation and standard entropies of the CdAs2 and α-Cd3As2 compounds, were calculated. A comparative analysis of obtained results with literature has been carried out.
