- Аннотация: A comprehensive study of solid-phase equilibria in the system Cu-Sb-S and thermodynamic properties of copper antimony sulfides was conducted by the powder x-ray diffraction technique, differential thermal analysis and electromotive forces (EMF) methods. The phase diagram of the system at 300 K constituting Cu3SbS4, CuSbS2, Cu3SbS3, Cu12Sb4S13 and Cu14Sb4S13 ternary compounds was built. Some components of the presented phase diagram differ from the previous works. From the data of EMF measurements of the concentration cells relative to the Cu electrode with a solid electrolyte Cu4RbCl3I2, the partial thermodynamic functions of copper in some phase regions of the Cu-Sb-S system and the standard thermodynamic functions of formation and the standard entropies of the ternary compounds were determined experimentally for the first time.
