Glasses in the xAl2O3·(40 − x)Ag2O·60P2O5 system were prepared using melt quenching rout, where x varies between 0 and 20 mol%. Scanning electron microscopy indicates that the addition of Al2O3 has changed the morphology of the samples under investigation. The density of the glasses and the corresponding molar volume are both decreased linearly with increasing content of Al2O3. The dissolution rates (Dr) of the studied glasses were determined using weight loss method. Dr has showed a strong decreasing trend (from ~ 10−4 to ~ 10−9) upon increasing Al2O3 content. By increasing the concentration of Al2O3, the chemical durability of the investigated glasses is increased. Decreasing the weight loss was interpreted in terms of increasing concentration of P–O–Al bonds in the glasses investigated. The activation energy for ionic conduction showed an increasing behavior with increasing Al2O3 contents.

Al2O3–Ag2O–P2O5 玻璃的化学耐久性和结构

xAl2O3·(40-x)Ag2O·60P2O5 系统中的玻璃是使用熔体淬火工艺制备的，其中 x 在 0 到 20 mol% 之间变化。扫描电子显微镜表明，Al2O3 的添加改变了所研究样品的形态。随着Al2O3含量的增加，玻璃的密度和相应的摩尔体积均呈线性下降。所研究玻璃的溶解速率 (Dr) 使用失重法测定。随着 Al2O3 含量的增加，Dr 显示出强烈的下降趋势（从~10-4 到~10-9）。通过增加 Al2O3 的浓度，所研究玻璃的化学耐久性增加。减少重量损失被解释为增加所研究玻璃中 P-O-Al 键的浓度。
