Strengthened Glass Articles Having Improved Survivability

摘要

Embodiments relate to a tempered glass article, wherein the tempered glass article has a thickness t ≤ 1 mm (1000 μm), an inner region under central tensile CT (in MPa), and an inner region adjacent the inner region and from a surface of the tempered glass article at least one compressive stress layer extending to a depth of layer DOL (μm) within the tempered glass article, wherein the tempered glass article is under a compressive stress CS s (in MPa) at the surface, wherein the tempered glass article is 0- an alkali aluminosilicate glass article comprising 5 mol % Li 2 O, at least 3 mol % Al 2 O 3 , and at least 5 mol % Na 2 O, wherein DOL > 90 μm, and CS s /DOL ratio > 2.5 MPa/μm.
