Synthesis structural and thermal properties of 30Li2O-20ZnO-xB2O3-(50-x) P2O5 borophosphate glasses with varying B2O3 content

[Display omitted] •New borophosphate glass materials (30Li2O-20ZnO-xB2O3-(50-x) P2O5) were synthetized with varying concentrations of B2O3.•Glasses Synthesized were characterized by XRD, DSC, SEM/EDS and Raman spectroscopy.•Introduction of the B2O3 resulted in a gradual conversion from trigonal [BO3] to tetragonal [BO4]. A borophosphate system with the composition 30Li2O-20ZnO-xB2O3-(50-x) P2O5 (where x = 0, 10, and 45 mol%) has been successfully synthesized using the conventional melt-quenching technique. The resulting materials were analyzed for their amorphous and vitreous properties using X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The study focused on the impact of boron doping on thermal properties, specifically examining the glass transition temperature (Tg), crystallization temperature (Tc), and overall thermal stability. Structural analysis was further supported by Raman spectroscopy, providing insights into the network structure of the glasses. Morphological characteristics and elemental composition were analyzed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS).
