This study reports that MoO3 doped glasses (LBB) are produced by a melting traditional process and using the XRD diffractometer technique to check their states. FTIR spectral analysis has examined the functional groups of the glass matrix. FT-IR spectrums reveal that the BO3, BO4. BiO6 and MoO6 octahedral have been built up and structural unit BO3 was transformed into BO4. The mechanical characteristics were linked to the FT-IR spectrum results. Ultrasonic velocities, elastic modulus, density, and thermal stability increased, while molar volume decreased. The increase in these parameters is linked with [BO4] the formation of structural units, an increase the strength of Mo – O, and force constant is higher than Li – O, so glass rigidity increases. Therefore, the increase of MoO3 usually has a significant influence on the bridging oxygen (BO) formation in BBL glasses. The increase in thermal stability connected to an increase in average force constantly, and the replacement of Li–iO with Mo–O linkages. The bond dissociation energy of Li–Li (137.3 ± 6.3 kJ/mol) is much weaker than the dissociation energy of Mo–Mo (449 ± 1 kJ/mol). Lithium borate Li2B4O7 (diomignite) has been identified in all formed glass–ceramics. With the increasing MoO3, the intensity of diomignite diffraction peaks (Li2B4O7) was reduced and transformed into a less stable lithium borate (Li2B2O5) phase.
