Dependence of N4 upon alkali modifier in binary borate glasses
In this paper we re-examine the alkali dependence of the fraction of four-coordinated borons (N4) in two series of glasses: alkali borates (0·4M2O.B2O3) and mixed lithium caesium borates (0·4(xLi2O+(1-x)Cs2O). B2O3). High field B MAS-NMR experiments were performed to maximise the accuracy of the present results. We found no evidence for an alkali dependence on N4 in either system. In each case ...
متن کامل“Universal” curve of ionic conductivities in binary alkali borate glasses
Since the discovery of fast ionic conductivity in glasses, there has been a large interest in explaining the diffusion mechanism. With this knowledge one may be able to design new glasses with optimized properties for various applications. It is well known that the ionic conductivity increases rapidly when a network glassformer is modified by the addition of a metal alkali. Despite considerable...
متن کاملMultilevel Tunnelling Systems and Fractal Clustering in the Low-Temperature Mixed Alkali-Silicate Glasses
The thermal and dielectric anomalies of window-type glasses at low temperatures (T < 1 K) are rather successfully explained by the two-level systems (2LS) standard tunneling model (STM). However, the magnetic effects discovered in the multisilicate glasses in recent times, magnetic effects in the organic glasses, and also some older data from mixed (SiO₂)(1-x) (K₂O)(x) and (SiO₂)(1-x) (Na₂O)(x)...
متن کاملSPECIATION AND LOCAL STRUCTURE IN ALKALI AND ALKALINE EARTH SILICATE GLASSES: CONSTRAINTS FROM 29Si NMR SPECTROSCOPY
‘?Si NMR spectroscopy provides important contributions to the understanding of silicate glass structure. as the resonance frequency is sensitive to several aspects of the local chemical environment (including intertetrahedral bond angles. bond distances. and number of bridging oxygens per silicon atom). New data on a series of binary alkali and alkaline earth glasses are presented which highlig...
متن کاملThe cationic energy landscape in alkali silicate glasses: Properties and relevance.
Individual cationic site energies are explicitly determined from molecular dynamics simulations of alkali silicate glasses, and the properties and relevance of this local energetics to ion transport are studied. The absence of relaxations on the time scale of ion transport proves the validity of a static description of the energy landscape, as it is generally used in hopping models. The Coulomb...
