Abstract—

When water diffuses into silica glass it reacts chemically forming nanometre sized pores that change the physical properties of the glass, for example, affect its strength. Here we discuss the effect of water on Young’s modulus, and show how it is reduced by the water reaction, whereby a proportional behaviour applies to small amounts of water involved in the reaction. The value of the elastic modulus will be not linear with the hydroxyl-quantity in the glass for very high concentrations. The relationship between hydroxyl concentration and Young’s modulus can be determined from measurements of sound wave velocity and will be represented by damage and pore models from literature.

二氧化硅中羟基产生的损害

摘要-

当水扩散到石英玻璃中时，它会发生化学反应，形成纳米级的细孔，这些细孔会改变玻璃的物理性质，例如影响玻璃的强度。在这里，我们讨论水对杨氏模量的影响，并显示水如何通过水反应将其还原，从而成比例的行为适用于反应中涉及的少量水。对于非常高的浓度，弹性模量的值与玻璃中的羟基量不是线性的。羟基浓度和杨氏模量之间的关系可以通过声波速度的测量来确定，并且可以通过文献中的损伤和孔模型来表示。
