【摘要】 研究了通过离子交换提高Ｋ２Ｏ－ＰｂＯ－ＳｉＯ２系统玻璃的表面化学稳定性，研究各种阳离子对该系统玻璃表面化学稳定性影响规律，找出了最佳离子及工艺条件。离子交换后，玻璃的化学稳定性普遍提高了４～７倍。更多还原

【Abstract】 ?A study on improving surface chemical durability of K2O-PbO-SiO₂ glass was conducted by ion exchange process. The influnce of various cations on the surface chemical durablility was studied. The optimun cations and technology were chosen. The chemical durability of the glass was increased by 4～7 times through ion exchange process.更多还原
