Multi-Nuclear Nmr Studies Of Borosilicophosphate Glasses And Microfoams

Glasses in the ternary Si02-B203-P205 system have a compositional region encompassed by 40-75 mol% Si02, 10-40 mol% B203 and 10-35 mol% P205, in which glass-ceramics containing BP04 crystallites can be formed. This system is also interesting in that all of the constituents are traditional glass formers. Nuclear magnetic resonance (NMR) spectroscopy has been used to examine the cation speciation and hydrogen evaluation in this multi-glass former system.
