The influence of Bi2O3 on the thermal and structural properties of lithium cadmium borate glasses with the composition 30Li2O•20CdO•xBi2O3•(50-x)B2O3 (0 < x < 50 mol%) was investigated. Glass samples were synthesized using the conventional melt-quenching technique and analyzed through DSC, and FTIR spectroscopy. Density (Dg) and molar volume (Vg) variations suggest structural transitions in the glass network at approximately30 and 40 mol% Bi2O3. FTIR and thermal studies indicate that Bi3⁺ ions primarily occupy octahedral positions for x > 30 mol% and both octahedral and pyramidal positions for x ≥ 30 mol%. The incorporation of heavy metal ions promotes the conversion of sp2 planar triangular [BO3] units into more stable sp3 tetrahedral [BO4] units, accompanied by an increase in non-bridging oxygens. The glass stability parameter (Δ) confirms the thermal stability of the prepared glasses.
