Chalcogenide glasses in the pseudo-ternary system NaX–GeS{sub 2}–Ga{sub 2}S{sub 3} (X=Cl or I) were synthesized. Different series were investigated in order to highlight the influence of the sodium halide addition on two different host glasses (GeS{sub 2}){sub 80}(Ga{sub 2}S{sub 3}){sub 20} and (GeS{sub 2}){sub 72}(Ga{sub 2}S{sub 3}){sub 28}. Macroscopic properties including density and characteristic temperatures, such as glass transition temperatures T{sub g} and crystallization temperature T{sub x}, were determined for a maximum molar content of NaX equal to 15%. The evolution of the optical band-gap and the chemical stability following the composition were also studied. Conductivity measurements were also performed and compared to other Li-based GeS{sub 2}–Ga{sub 2}S{sub 3} glasses. The results were discussed taking into account the cation and anion nature and also the glass packing density. - Graphical abstract: Characterizations of NaX–GeS{sub 2}–Ga{sub 2}S{sub 3} chalcogenide glasses (X=Cl or I). - Highlights: • Synthesis and characterization of NaX–GeS{sub 2}–Ga{sub 2}S{sub 3} chalcogenide glasses (X=Cl or I). • We compare results with analoguous LiX-bearing glasses. • Correlation between electrical conductivity and glass packing density.
