一种玻璃组合物及其制备方法和应用
摘要：
本公开公开了一种玻璃组合物，以所述玻璃组合物的总摩尔数值为100％计，所述玻璃组合物包括40‑65mol％的SiO2、10‑22mol％的Al2O3、3‑18mol％的P2O5、12‑20mol％的Na2O和0.01‑5mol％的ZnO；所述玻璃组合物具有较高的杨氏模量，适合于化学强化工艺，强化后的玻璃机械性能好，抗破坏和跌落。本公开还提供了所述玻璃组合物的制备方法和应用，经过化学强化后的玻璃组合物具有较高的压缩应力与断裂韧性，适用于各种触摸屏设备，尤其是曲面显示屏设备。
摘要（英）：

The invention discloses a glass composition. The glass composition comprises, by mole, 40-65mol% of SiO2, 10-22mol% of Al2O3, 3-18mol% of P2O5, 12-20mol%of Na2O and 0.01-5mol%of ZnO. The glass composition has high Young's modulus and is suitable for chemical strengthening process, and glass after strengthening are good in mechanical properties and resistant to damage and dropping. The invention further provides a preparation method and application of the glass composition. The chemically strengthened glass composition has high compressive stress and fracture toughness and is applicable to various touch screen devices, in particular to curved surface display devices.
