Book excerpt: Four models have been applied to a data base to relate glass dissolution in distilled water to composition. The data base is used to compare the precisions obtained from the models in fitting actual data. The usefulness of the data base in formulating a model is also demonstrated. Two related models in which the composite or pH-adjusted free energy of hydration of the glass is the correlating parameter are compared with experimental data. In a structural model, the nonbridging oxygen content of the glasses is used to correlate glass dissolution rate to composition. In a model formulated for this report, the cation valence and the oxygen content of the glass are compared with observed dissolution rates. The models were applied to the 28-day normalized silica release at 90/sup 0/C for over 285 glass compositions with surface area to volume ratios of 10 m/sup -1/ (Materials Characterization Center MCC-1 glass durability test using distilled water). These glasses included the nonradioactive analogs of WV205 and SRL-165, as well as SRL-131, PNL 76-68, and a European glass, UK209. Predicted glass dissolution rates show similar fits to the data for all four models. The predictions of the models were also plotted for two subsets of the glasses: waste glasses and Savannah River Laboratory glasses. The model predictions fit the data for these groups much better than they fit the data for the entire set of glasses. 14 refs., 12 figs., 7 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this PhD study are to gain insights into mass transport-related properties, e.g., glass transition temperature, Vickers hardness, and activation energy of dynamic dissolution, of mixed modifier aluminosilicate glasses and gain a coherent understanding of the mechanism of mass transfer. The primary objective is to propose and apply an experimental framework that can be capable of predicting these properties for multicomponent glasses containing mixtures of network modifiers. Pairwise and ternary interactions are examined experimentally to understand the mixed modifier effect (MME) in a series of ternary modifier containing (Na2O·K2O·CaO) aluminosilicate glasses. The pairwise model follows from the work of LaCourse [LaCourse WC. A defect model for the mixed alkali effect. J Non-Cryst Solids. 1987;95-96:905--912.]. By keeping the glass network former concentration constant and adjusting the molar ratios of the three network modifiers, the glass transition temperature (Tg), Vickers hardness (Hv) and activation energy (Ea) for aqueous dissolution of each modifier cation are investigated. We examine whether the pairwise interaction model is sufficient, or if ternary interactions also need to be included to predict the MME in these more complicated glass systems. This work reveals that the pairwise model can be used to predict the mixed modifier effect for Tg in complex multiple-modifier glass system by solely using a combination of binary systems involving the two-body interaction factors. However, ternary mixed-modifier interactions are present in other properties such as Hv and Ea. The outcomes suggest pathways that could be used to improve the chemical durability of aluminosilicate glasses by compositional alternations that enhance network rigidity.
