The discrimination of protonated Si sites by CP MAS was also used by Yang and Kirkpatrick (1989) in a study of the hydrothermal decomposition of albite and sodium aluminosilicate glass, and rhyolitic glass (Yang and Kirkpatrick 1990), and as a means of differentiating between the various sites in acid-treated montmorillonites (Tkac et al. 1994). CP MAS NMR has also been used to identify a Si site at -100 ppm in a microporous material derived from acid-leached metakaolinite as the unit Si(0Si)30H (Okada et al. 2000). [Pg.229]

Ab initio calculations have been made of H, O, A1 and Si NMR parameters for sodium aluminosilicate glasses and hydrous silica.331 Two-dimensional 170 3Q MAS-NMR experiments on sodium aluminosilicate glass gave evidence for A1 O Al links.332 27A1 NMR spectra were used to study structural localisation of Al3+ in aluminosilicate clays.333 170 MAS-NMR and MQ MAS-NMR experiments have been carried out on hybrid aluminosilicate xerogels, providing evidence for Si-O-Al and Si O Si sites.334 Several other NMR studies have been made on aluminosilicate glasses and related systems.335 338... [Pg.146]

An additional electrolyte can also provide the auxiliary electrode function. For example, Na2CO3 can be used with NaP alumina [135-137], NASICON [138-146], or a sodium aluminosilicate glass [147] as the electrolyte for a CO2 sensor, in which case the Na2CO3 equilibrates with CO2 in the gas and Na in the electrolyte according to the following reaction ... [Pg.444]

Pressure-induced structural changes and the extent of disorder in aluminosilicate glasses and melts at high pressure remains a challenge in modern physical and chemical sciences. A1 and 0 3QMAS NMR spectra were obtained for sodium aluminosilicate glasses quenched from melts at pressures up to 8 GPa. [Pg.337]

As expected, given the above review, one of the principal apphcations of XPS in the study of glass corrosion, is the evolution of surface composition throughout the corrosion process. In particular, it has been shown erqrerimentally, an alkali and/or alkaline-earth depleted leached layer forms on the surfaee of a glass reacted in a variety of aqueous and/or humid envirorunents [13-15, 25-28]. For example, figure 7 shows the surfaee eomposition of a calcium-sodium aluminosilicate glass reacted in an acidic solution as a fimction of time. [Pg.7]

Electrode structure is shown in Figure 6.6. It can be fabricated by bonding a short length of special sodium aluminosilicate glass to a piece of lead glass tubing. The end is then closed in a flame and blown to form the bulb. The filling electrolyte may be either O.In NaCl solution or 0.1 n HCl. Electrical contact is made via a silver-silver chloride electrode (chloridized... [Pg.125]
