InxBi40−xSe60 (x = 1.6, 4.4, 7, 10 and 13.2) alloys were synthesized by melt-quenching technique. The X-ray diffraction and Raman spectroscopy investigations confirm that the materials are in single phase. Archimedes method and Energy Dispersive Spectroscopy (EDS) have been used for density and chemicalcharacterization of the obtained materials. Indium content dependences of different parameters such asthe density (D), the compactness (ı), and the average coordination number (Z) have been investigatedand discussed in light of chemical order network and topological models.
