Full text linkIntermediate-Range Order of Alkali Disilicate Glasses and Its Relation to the Devitrification Mechanism
Full text linkMAS NMR as a probe for investigating the distribution of Si---O---Si angles in lithium silicate glasses
No full textMagic-angle-spinning NMR has been used to study Si---O---Si bond-angle distributions associated with various structural elements, Qn, present in lithium silicate glasses of different compositions. It is shown that glasses contain a plurality of structural elements with a broad distribution of Si---O---Si bond angles, and that the width of the distribution is characteristic of a particular Qn specie
