一种中铝及高铝硅酸盐玻璃化学强化用熔盐及使用其进行化学钢化增强的方法
摘要：
本发明提供一种中铝及高铝硅酸盐玻璃化学强化用熔盐，所述熔盐组成包括KNO3、KOH、KCl以及K2CO3，所述熔盐中KOH与K2CO3的质量比为0.05～0.4，KCl与K2CO3的质量比为0.075～1.0，KNO3与K2CO3的质量之比为100:1.0～4.0。本发明还提供一种使用所述的中铝及高铝硅酸盐玻璃化学强化用熔盐进行化学钢化增强的方法。本发明的熔盐配方指出了适合中铝与高铝玻璃化学强化的配方组成范围，使用该配方可以避免玻璃表面的腐蚀，保证化学强化后的玻璃具有较高的透过率；同时，使用本发明的配方还可以极大地提高化学强化后玻璃的表面应力与应力层深度。
摘要（英）：

The invention provides a fused salt for chemically enhancing medium-aluminum and high-aluminum silicate glass. The fused salt comprises the following compositions: KNO3, KOH, KCl and K2CO3, wherein a mass ratio of KOH to K2CO3 in the fused salt is 0.05-0.4; a mass ratio of KCl to K2CO3 is 0.075-1.0; and a mass ratio of KNO3 to K2CO3 is 100:(1.0-4.0). The invention further provides a method for performing chemically toughened enhancement by using the fused salt for chemical enhancing of medium-aluminum and high-aluminum silicate glass. The fused salt formula disclosed by the invention indicates a formula composition range suitable for chemical enhancing of the medium-aluminum and high-aluminum glass. According to the formula, corrosion on the glass surface can be avoided, and the chemically enhanced glass has high transmittance; and meanwhile, due to the formula disclosed by the invention, the surface stress and stress layer depth of the chemically enhanced glass can be greatly improved.
