An investigation of (100-x)[0.5PbO-0.2B2O3-0.3P2O5]-xMoO3 glasses
Original language description
Lead borophosphate glasses of the composition (100-x)[0.5PbO-0.2B2O3-0.3P2O5]-xMoO3 with 0-70 mol% MoO3 were prepared and studied. Thermal studies were carried out with DTA and dilatometry. The glass transition temperature in these glass series decreasessteadily with increasing MoO3 content from 467 to 342oC within the range of x = 0-70. The glass structure was studied by 31 P and 11B MAS NMR and by Raman spectroscopy. These studies were devoted to the investigation of changes in boron coordination inthe dependence on changes of MoO3 content and of the B2O3/P2O5 ratio. When the molybdenum oxide and boron oxide content is low, tetrahedral BO4 units prevail in the structural network. With higher B2O3 content as well as with higher MoO3 content, trigonal BO3 groups are also formed. 11B MAS NMR spectra of BO4 units in the glasses with a low boron content reveal two symmetrical signals of BO4 units, ascribed to B(OP)3O and B(OP)2O2 units with B-O-P and B(4)-O-B(4) bonds. In the 11B spectr
