制备强化的锂基玻璃制品的方法和锂基玻璃制品
摘要：
揭示了玻璃制品的强化方法和通过该方法形成的强化的玻璃制品。方法包括使玻璃制品与离子交换溶液接触约4‑8小时。离子交换溶液的温度约为370‑410℃。离子交换溶液包括约65‑75摩尔％KNO3和约25‑35摩尔％NaNO3。在接触之前，玻璃制品的组成是：约55摩尔％至约75摩尔％SiO2、约8摩尔％至约15摩尔％Al2O3、约5摩尔％至约12摩尔％Na2O、约8摩尔％至约14摩尔％Li2O；0摩尔％至约1摩尔％K2O、0摩尔％至约2摩尔％MgO、0摩尔％至约2摩尔％CaO、和0摩尔％至约2摩尔％ZrO2。
摘要（英）：

A method for strengthening a glass article and strengthened glass articles formed from the method are disclosed. The method includes contacting the glass article with an ion exchange solution for about 4 hours to about 8 hours. The ion exchange solution has a temperature from about 370° C. to about 410° C. The ion exchange solution includes about 65 mol. % to about 75 mol. % KNO3 and from about 25 mol. % to about 35 mol. % NaNO3 Prior to the contacting, the glass article has a composition of about 55 mol. % to about 75 mol. % SiO2, about 8 mol. % to about 15 mol. % Al2O3, about 5 mol. % to about 12 mol. % Na2O, about 8 mol. % to about 14 mol. % Li2O; 0 mol. % to about 1 mol. % K2O, 0 mol. % to about 2 mol. % MgO, 0 mol. % to about 2 mol. % CaO, and 0 mol. % to about 2 mol. % ZrO2.
