Abstract

The structural parameters, the axial thermal expansion coefficients and the characteristic Debye temperatures for the order vacancy compound CuGa~5~Se~8~ with the chalcopyrite‐related structure, prepared by the Bridgman technique, were determined at different temperatures between 90 and 650 K by the X‐ray diffraction method. The melting point of this compound was defined from the differential thermal analysis data. The anisotropy of thermal expansion in CuGa~5~Se~8~ is shown to exist with the coefficients along a‐axis being larger than those along the c‐axis throughout the temperature range studied.
