The elements of structural network of the five‐component chalcogenide glasses from the pseudo‐binary system (As2Se3)100−x(SbSI)x have been investigated by high‐temperature X‐ray powder diffraction analysis. Appearance of a large number of structural units in the crystallization processes above glass transition temperature Tg was observed. The DSC experiments shows that the temperature regions of crystallization translates to lower temperatures with increasing SbSI content. Structural unit of SbSI, which in the monocrystal form is a ferroelectric, exists in materials with x⩾50 at. %.
