The Structure of Oxide Glasses: Insights from 17O NMR

  • Philip J. Grandinetti

As a probe of local structure in network forming oxide glasses, 17O nuclear magnetic resonance (NMR) spectroscopy has been an invaluable tool [1-10]. The analysis of oxygen in these glasses is vital because their structure predominately consists of well-defined cornersharing SiO4 tetrahedra connected in a continuous infinite three-dimensional network lacking long-range order. The interconnection of two tetrahedra involves a Si-O-Si bond angle, and two dihedral angles, and the variation in these angles is considered to be one of the main sources of disorder in a conventional melt quenched silicate glass.
