local structure of alkaline earth boroaluminate crystals and glasses ii 11b and 27al mas nmr spectroscopy of alkaline earth boroaluminate glasses
Journal of the American Ceramic Society, 1991Co-Authors: Bruce C Bunker, James R Kirkpatrick, Richard K Brow, Gary L Turner, Carolyn NelsonAbstract:11B and 27Al magic angle spinning nuclear magnetic resonance (MAS NMR) spectra of alkaline-earth boroaluminate glasses show that the structure of these glasses are far more complicated than previously thought. The relative concentrations of 3- and 4-coordinated boron vary as found by previous investigators using continuous-wave NMR methods, but the 27Al NMR spectra indicate the presence of Al in 4-, 5-, and 6-fold coordination, in contrast to previous assignments. Analysis of the data based on local charge balance considerations provides a Qualitative Model that correctly predicts compositional variations of the NMR peak intensities and 27Al chemical shifts for a wide range of boroaluminate glass compositions.
