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 self-irradiation 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 AlO₄ groups are then Ca-compensated, while a part of BO₄ is transformed into BO₃ 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.

尽管越来越了解氧化硅玻璃组合物对其化学耐久性的影响，但对结构的贡献了解得很少，但对于精确描述水蚀变机理至关重要。可以通过改变玻璃的热历史来研究结构紊乱的影响。此外，可以将核玻璃中自辐照产生的结构变化与快速淬火引起的结构变化进行比较。在玻璃基质的深层地质处置的背景下，解决结构对玻璃耐久性的影响是具有挑战性的。在这里，将硼硅酸盐玻璃（国际简单玻璃）纤维化以获得快速淬火的样品。从原位拉曼光谱和布里渊光谱学评估淬灭速率和虚拟温度。多核核磁共振用于深入了解淬火对原始和改变的玻璃结构的影响。在快速淬火玻璃中观察到较高的键角分布和较低的碱混合。一些AlO然后对_4个组进行Ca补偿，同时将BO ₄的一部分转换为BO ₃单位。在90°C的正向速率下，结构改变会增加硅酸盐网络的水解程度，取决于pH值的1.4至1.8倍。在二氧化硅饱和溶液中进行的实验开始时，残留速率机制也受到类似的影响。这些发现证明，在各种改变方案下，玻璃的反应性仍受其结构控制。
