[sup 31]P and [sup 27]Al MAS NMR investigations of some lead phosphate glasses. [Magic Angle Spin Nuclear Magnetic Resonance]
- Shanghai Jiao Tong Univ. (China). Dept. of Materials Science and Engineering
The [sup 31]P MAS NMR spectra were measured and analyzed for the two phosphate glasses that contain distinct metals (i.e., In or Ba), different amounts of PbO, and the same content of P[sub 2]O[sub 5] and Al[sub 2]O[sub 3]. The [sup 31]P MAS NMR spectra for the two glasses have a single isotropic peak at [minus]3.77 or [minus]4.76 ppm, indicating that orthophosphate species are the dominant P sites in the glasses studied. The [sup 27]Al MAS NMR spectrum measured for the lead-barium-aluminum phosphate 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)[sub 4] is the dominant moiety for the glass, suggesting the formation of orthophosphate species in the glass.
