LOW-MODULUS ION-EXCHANGEABLE GLASSES

摘要

Ion-exchanged alkali aluminosilicate glass articles with a ratio of peak compressive stress value to Young's modulus value of 14 or more. The glass articles may include Al2O3 mol% + RO mol% ≥ 18 mol%, where RO mol% = MgO mol% + CaO mol%, and be substantially free of ZnO, SrO, BaO, B2O3, P2O5, Li2O, and K2O. The glass articles may have a peak compressive stress value in a range of 850 MPa to 1400 MPa. The glass articles are suitable for various high-strength applications, including cover glass applications that experience significant bending stresses during use, for example, cover glasses for flexible displays.
