| 摘 要： | 通过测试新型磷酸盐玻璃在酸性介质中质量损失随时间的变化情况，讨论并比较了玻璃在酸性介质中的化学侵蚀机理。研究表明：玻璃在酸性介质中经过一段线性溶解过程中，玻璃的溶解速率有所下降。这是由于玻璃表面生成明显覆盖层所致。XRD图谱显示覆盖层的组分和结构与玻璃完全一致。

| Abstract: | A new phosphate glass for precision molding was developed. The mass loss of the phosphate glass in acid media was measured and the corrosion mechanism in acid media is discussed. The results show that during initial dissolution the disolution rate of the glass versus time is linear. But when ionic strength of the leaching solution increases, the dissolution rate decreases because of the presence of a hydrated layer, whose composition and structure is identical to those of glass. |
