Abstract
The 31P- and 27Al-MAS-NMR spectra of a lead-barium-aluminum phosphate glass were measured and analyzed, and the short range structure of the glass are discussed. The 31P-MAS-NMR spectrum of the glass studied has a single isotropic peak at -4.76 ppm, indicating that orthophosphate species are the dominant P-sites in the glass. The 27Al-MAS-NMR spectrum of the glass shows that the aluminum ions present in the glass are in 4-, 5-, and 6- fold coordination with oxygen, and that the Al(OP)4 is the dominant moiety for the glass, suggesting the formation of orthophosphate species in the glass.
