Abstract: A new phosphate glass with the composition (50-x)K2O-xMoO3-50P2O5 was developed using the standard melt-quenching technique. X-ray powder diffraction was used to confirm the amorphous character of the glass samples. Differential scanning calorimetry was used to determine the glass transition temperature. The Tg values drop from 451°C for x = 0 mol% to 363°C for x = 40 mol%. Indeed, density, molar volume, and chemical dissolution are also studied. The results suggest that adding molybdenum oxide increases chemical dissolution and density while decreasing molar volume. Structural variations in the function of MoO3 content were carried out by FT-IR and Raman spectroscopic data. Molybdenum oxide is assumed to break the structural glass network into pyrophosphate groups, making it more depolymerized and open. The microstructure of glass materials is examined by Scanning Electron Microscopy (SEM) coupled with an EDX. The elements that composed the samples were all identified.
