Si-29 T-1 relaxation in alkali silicate glasses: a method for detecting glass-in-glass phase separation
UNSPECIFIED. (2001) Si-29 T-1 relaxation in alkali silicate glasses: a method for detecting glass-in-glass phase separation. JOURNAL OF NON-CRYSTALLINE SOLIDS, 281 (1-3). pp. 108-116. ISSN 0022-3093Full text not available from this repository.
High resolution nuclear magnetic resonance (NMR) has been used to measure relaxation times, T-1, in alkali silicate glasses. Two-component relaxation was observed in lithium silicate glasses. In glasses close to the sodium disilicate composition, the relaxation was one component but, with decreasing sodium content, this becomes two component. In heat-treated sodium silicate glasses two components appear to grow from the single component and the extent of growth depends upon the heal-treatment temperature and time. The results for all systems are explained in terms of phase separation and all insight into the Q " distribution is also presented. (C) 2001 Elsevier Science B.V. All rights reserved.
