“…Solid-state NMR has been particularly effective in unveiling atomic structures of multi-component glasses (Oestrike and Kirkpatrick, 1988;Eckert, 1994;Stebbins, 1995). Because high-resolution NMR is the main experimental tool Goel et al (2008).…”

“…The predicted NBO fraction [NBO/(NBO + BO)]-the degree of network polymerization-varies from 0.67 (X Diopside = 1) to 0 (X Diopside = 0) (Eckert, 1994): the NBO/T (the number of non-bridging oxygens per tetrahedral network cation) values for CMAS glasses in the join, predicted from the composition, change from 2 (X Diopside = 1) to 0 (X Diopside = 0) ( Table 2). We also note that because the structures explored here were those of glasses quenched from melts, the structures studied here represent the atomic configurations of super-cooled liquids and at the glass-transition temperature, below which the melt structure is frozen.…”

“…Important new insights were also obtained on the structural role of the intermediate oxide Al 2 O 3 in glasses 22 as summarized in a review article from that period. 23 Further scientific highlights were the detection and quantification of unusual coordination states (five-and six-coordinate Al and Si) in glasses prepared under high-pressure conditions 24 and with special chemical compositions. 25 To the present date, multinuclear MAS-NMR remains a standard part of glass structural characterization.…”

Glasses remain a focus of attraction to fundamental researchers and materials engineers alike. The desire of controlling physical property combinations by compositional design inspires the search for fundamental structural concepts describing the short‐ and medium‐range order of the glassy state. From its early beginnings more than 60 years ago, solid‐state nuclear magnetic resonance (NMR) spectroscopy has been making significant contributions toward this objective. Being element‐selective, inherently quantitative as well as selective to the local environment, NMR in many ways presents an ideal experimental tool of structural investigation of glasses. Over the years, substantial NMR methods development, along with advances in the theoretical interpretation of NMR parameters, have significantly enhanced our fundamental knowledge of medium‐range order and of composition‐structure‐function relationships. As we are approaching the 60th anniversary of the publication of the first article dealing with this topic (A.H. Silver and P.J. Bray, The Journal of Chemical Physics 1958, 29, 984), it is time to look back at the amazing scientific trajectory this field of investigation has taken, from the early beginnings to the present state of the art. As such, this overview does not strive to be comprehensive, but adopts a personal perspective, highlighting what in the view of the author have been influential developments and important insights obtained during the various phases of scientific inquiry in this research field.
