Structure and properties of lead borophosphate glasses doped with molybdenum oxide

Popis výsledku v původním jazyce

Lead borophosphate glasses doped with MoO3 were studied in two compositional series (1-x)[50PbO-10B(2)O(3)-40P(2)O(5)]-xMoO(3) with a constant B2O3/P2O5 ratio and (1-x)[50PbO-yB(2)O(3)-(50-y)P2O5]-xMoO(3) with 0, 20, 40 and 60 mol% MoO3. Some physical properties were measured and their structure was studied by P-31, B-11 MAS NMR and Raman spectroscopies. Thermal behaviour was studied by DTA and dilatometry. The glass transition temperature in the series (1-x)[50PbO-10B(2)O(3)-40P(2)O(5)]-xMoO(3) has a maximum at x=0.3, whereas the thermal expansion coefficient has a minimum at x=0.4. The highest thermal stability was observed in glasses with x=0.1-0.2. Structural studies were devoted to an investigation of boron coordination versus MoO3 content and theB2O3/P2O5 ratio. According to the NMR spectra, molybdenum atoms in borophosphate glasses preferentially form P-O-Mo bonds. Tetrahedral BO4 units predominate in the studied borophosphate glasses at a low MoO3 content. B-11 MAS NMR reveale
