Abstract

This study compares the mechanical properties of chemically strengthened borosilicate glass vials (BSGV) and Corning's aluminosilicate glass vials (Valor®). A trade-off exists in BSGV between surface compressive stress (CS) and depth of layer (DOL), varying with temperature and strengthening duration. Compared with Corning’s Valor®, ion-exchanged BSGV exhibited up to 55 % lower CS (at 500 °C for 4 h) and 89 % lower DOL (at 400 °C for 1 h). These variations derive from sodium content differences and the glass structural network; however, both ion-exchanged BSGV and Valor® demonstrated internal pressure (IP) strengths surpassing the 60 bar limit of our testing equipment at 450 and 500 °C. BSGV undergoes strengthening at 400 and 450 °C for extended durations, gradually enhancing hardness (Hv) and elastic modulus (E). BSGV strengthened for 4 h at 450 °C showed mechanical properties approaching those of Valor®. Conversely, at 500 °C, prolonged strengthening times caused reductions in Hv and E owing to the rearrangement of the network structure and stress relaxation.

通过化学强化增强硼硅玻璃小瓶

本研究比较了化学强化硼硅酸盐玻璃小瓶（BSGV）和康宁铝硅酸盐玻璃小瓶（Valor®）的机械性能。在BSGV中，表面压应力（CS）与层深（DOL）之间存在一种权衡关系，随温度和强化时间而变化。与康宁的Valor®相比，离子交换BSGV的CS（在500°C下放置4小时）降低了55%，DOL（在400°C下放置1小时）降低了89%。这些差异源于钠含量的差异和玻璃结构网络；然而，离子交换BSGV和Valor®的内压（IP）强度都超过了我们的测试设备在450和500°C下的60 bar极限。BSGV在400°C和450°C进行长时间强化，逐渐提高硬度（Hv）和弹性模量(E)。BSGV在450°C下强化4 h，其力学性能接近Valor®。相反，在500℃时，由于网络结构的重排和应力松弛，延长强化时间导致Hv和E的降低。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
