“…6a provide more accurate information on the distribution of boron sites in the fibers. The distributions of isotropic NMR shifts are broader in the as-received fibers than in the annealed ones, for both BO 3 and BO 4 groups, as highlighted by the projections onto the isotropic NMR shift axis (Fig. 6b).…”

“…Typically, 1024 scans were accumulated. Two types of 11 B multiplequantum MAS experiments were carried out in order to optimize the signal obtained from BO 3 and BO 4 units, as described previously. 26 29 Si MAS NMR spectra were acquired using a saturation-recovery pulse sequence with a recovery delay of 20 s (increasing the recycling delay did not alter the lineshape).…”

While the influence of silicate oxide glass composition on its chemical durability is increasingly known, the contribution of structure only is less well understood, yet is crucial for an accurate description of aqueous alteration mechanisms. The effect of structural disorder can be investigated by varying the thermal history of the glass. Furthermore, the structural changes generated by selfirradiation in nuclear glasses can be compared with those induced by fast quenching. In the context of deep geological disposal of vitreous matrices, it is then challenging to address the structural impact on glass durability. Here, a borosilicate glass, the International Simple Glass, was fiberized to obtain a rapidly quenched sample. The quenching rate and fictive temperature were evaluated from in situ Raman and Brillouin spectroscopies. Multinuclear nuclear magnetic resonance was used to obtain insight into the effect of quenching on the pristine and altered glass structure. Higher bond angle distribution and lower mixing of alkalis were observed in the fast quenched glass. Some of AlO 4 groups are then Ca-compensated, while a part of BO 4 is transformed into BO 3 units. The structural modifications increase the hydrolysis of the silicate network occurring in the forward rate regime at 90°C by a factor of 1.4-1.8 depending on the pH value. Residual rate regime is similarly affected, more significantly at the beginning of the experiments conducted in silica saturated solutions. These findings prove that the reactivity of glass remains controlled by its structure under the various alteration regimes.

“…Optimizing their chemical durability is of primary importance to ensure the safety of the waste disposal. In the glassware and pharmaceutical industries, both borosilicate and aluminosilicate glasses are designed to contain liquid that must not be contaminated by glass components 7,8 . In nature, aluminosilicate glasses are massively produced by volcanoes and oceanic ridges 9 .…”

Can a simple topological-constraints-based model predict the initial dissolution rate of borosilicate and aluminosilicate glasses?

Tuning glass composition to obtain targeted properties generally relies on empirical approaches. However, a deep understanding of the physical and chemical mechanisms linking glass composition to its structure and properties would enable developing reliable predictive models. Indeed, although empirical models are usually able to interpolate composition-property relationships within a given compositional envelope, they often fail at extrapolating predictions far from their training domain. Here, as an alternative route to empirical models, we show that a structural descriptor based on the number of topological constraints per atom can be used to predict the initial dissolution rate of aluminosilicate and borosilicate glasses after being parameterized on different families of glasses (specific series of borosilicate glasses). Sixteen glasses belonging to these families were studied and their initial dissolution rates were determined at 90°C and pH 90°C = 9, covering rates spanning over 5 orders of magnitude. The model based on topological constraints was trained based on seven select borosilicate glasses (R 2 = 0.997) and used to predict the dissolution rate of nine additional borosilicate and aluminosilicate glasses. We show that, provided that corrections are made for high alkali content glasses that dissolve incongruently (preferential release of Na), the model gives reasonable predictions, even far from its training domain.npj Materials Degradation (2020) 4:6 ; https://doi.

“…The chemical characteristics of the Pb-O bond change from ionic character to more covalent when the PbO content increases above 30 mol% to better suit the needs of glass formation of oxide glass network. When the PbO content is increased to over 60 mol%, lead forms its own glassy structure, due to the properties of lead ions to produce glassy network over a wide range of concentrations up to more than 80 mol% PbO if the melt is cooled rapidly[49][50][51]. Pb ions leached from the glazed surfaces are therefore involved in the formation of the corrosion products detected by SEM.…”

A set of scientific methods (X-ray analyses, optical and electron microscopy, Raman spectroscopy and thermal analyses) was used for research of ceramic bodies and glazes of forty vessels from Renaissance Prague. The set of early modern age archaeological glazed ceramics contained tableware, kitchenware and technical ceramics. The main aim was to characterize ceramic materials and glazes over two centuries. Attention was also paid to identification of defects and corrosion products of the glazes. The research was conducted with an emphasis on the context of the original use of ceramic artefacts and the environment of waste pits from which they were excavated. Among the archaeological finding, three vessels of technical ceramics were found (a rectifier, a bowl and a jar) which together could have formed a distillation apparatus. Since these vessels represent a unique finding, they were subjected to a detailed survey. Based on the similarity of ceramic bodies and glazes, it was proved that the three vessels of technical ceramics were made in the same workshop and were parts of one distillation apparatus. The results of the performed analyses proved that the studied vessels were manufactured from raw materials with high content of a plastic component and that the raw materials did not change significantly during the period from 15th to 18th centuries. The firing temperature of most of the vessels did not exceed 1000 °C. It was proved that all glazes were middle- or high-lead glazes and were coloured with ionic pigments.
