Structure and properties of lead borophosphate glasses doped by molybdenum oxide
Original language description
Lead borophosphate glasses doped with MoO3 were studied in two compositional series (1-x)[50PbO-10B2O3-40P2O5]-xMoO3 with a constant B2O3/P2O5 ratio and (1-x)[50PbO-yB2O3-(50-y)P2O5]-xMoO3. Thermal behaviour was studied by DTA and dilatometry. Accordingto NMR spectra, molybdenum atoms in borophosphate glasses form preferentially P-O-Mo bonds. Tetragonal BO4 units dominate in the studied borophosphate glasses at a low MoO3 content. 11B MAS NMR revealed the formation of mixed tetrahedral units B(OP)4-n(OMo)n in the studied glasses. With an increase in the B2O3/P2O5 ratio and in the MoO3 content, the relative intensities of resonances ascribed to mixed tetrahedral units and trigonal BO3 units increase. 11B DQ NMR spectra revealed complex connectivity scheme between tetrahedral and trigonal units showing on the formation of BO4 units with B-O-P, B-O-Mo, B-O-BIV and B-O-BIII bonds.
