Abstract
The incorporation of molybdenum and sulfur in aluminoborosilicate glasses was studied. The base aluminoborosilicate glass is incapable of retaining Mo and S above the level of about 1 mol%, producing crystalline alkali molybdates and sulfates. The extent of molybdenum solubility was significantly improved by substituting phosphate for a small fraction of the silicate glass-network-formers, increasing Mo incorporation by a factor of three with 5 mol% P2O5, and to nearly five times the P-free glass solubility limit with the addition of 10 mol% P2O5. At the 5 mol% P2O5 additive level, both molybdenum and sulfur solubilities were simultaneously increased relative to the P-free glass, implying that their respective glass binding sites are independent. NMR measurements of the homogeneous Mo- and S-loaded glasses suggest that the phosphate network connectivity is key to their enhanced solubilities.
