Six glass compositions in the form 20Na2O–15BaO–10ZnO–(9–x) Fe2O3–xIn2O3–46P2O5 in which 0 ≤ X ≥ 9 mol% were synthesized using a traditional melting method at ambient conditions. In these glass systems, In2O3 was used to partly substitute Fe2O3. The impact of the In2O3 content on the structural, thermal, and mechanical properties of the glasses was investigated. Complete characterizations have been accomplished using XRD, DSC, and measurements of the density and molar volume. Elastic parameters including Poisson's ratio properties were also studied. The XRD patterns reflect the amorphous nature of the examined samples. The measured glass density was linearly increased (3.57–3.83 g/cm3), while the calculated molar volume was linearly decreased (34.48–34.11cm3/mol). The DSC examination points out that the indium ions mostly take part in network-forming positions and increase the rigidity of the glass network. Also, as inferred from the DSC data, the thermo-physical parameters Tg, Tp, and glass stability (∆GS) increased nearly proportionately as In2O3 was added, whereas the heat capacity change (∆Cp) was inversely related. Regarding the mechanical calculations, all elastic parameters decreased as a result of compositional In2O3/Fe2O3 modifications. Overall, these findings offer crucial insights into the intricate interplay between composition and properties in glasses, with potential implications spanning various fields, from materials science to engineering applications
