WO3-doped zinc borophosphate glasses
Original language description
The effect of WO3 on the properties and structure of zinc borophosphate glasses was investigated Homogeneous glasses of the composition (100-x)[0.5ZnO-0.1B2O3-0.4P2O5].xWO3 were obtained within the concentration range of x=0-40 mol% WO3, whereas glasseswith x=45 and 50 contain microinclusions of beta-WO3. Their glass transition temperature increases with increasing WO3 content, whereas the crystallisation temperature, and the thermal stability of the glasses reveal a maximum at 10-15 mol% WO3. The structure of the glasses was studied by Raman and infrared spectroscopy, combined with 31P and 11B MAS NMR spectroscopy. The Raman spectra are characterised by a strongly polarised band at 941-930 cm-1 and a depolarised band at 832-809 cm-1, ascribed to vibrations of WO6 and W-O-W bonds, respectively. Compositional changes in the 11B MAS NMR spektra reveal a partial conversion of BO4 to BO3 units with increasing WO3 content, and the replacement of B-O-P bridges by B-O-W bridges.
