GLASS-BASED ARTICLES WITH IMPROVED STRESS PROFILES

Abstract:

Glass-based articles comprise: a lithium-based aluminosilicate composition; a glass-based substrate having opposing first and second surfaces defining a substrate thickness (t), wherein t is less than or equal to 0.74 mm; and a stress profile comprising: a spike region extending from the first surface and comprising a spike depth of layer (DOL.sub.sp) located at a depth of greater than or equal to 7 micrometers; and a maximum central tension (CT.sub.max) of greater than or equal to 50 MPa.
