Abstract:
Embodiments of a glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0·t up to 0.3·t and from greater than 0.7·t, comprise a tangent that is less than about −0.1 MPa/micrometers or greater than about 0.1 MPa/micrometers, are disclosed. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0·t to about 0.3·t). In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a point between the first surface and the second surface and increases from the point to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness. Methods for forming such glass-based articles are also disclosed.

Claim (Index 1):
A glass substrate comprising:\n from about 68 mol. % to about 75 mol. % SiO 2 ; from about 0.5 mol. % to about 5 mol. % B 2 O 3 ; from about 1 mol. % to about 4 mol. % MgO; and from about 2 mol. % to about 10 mol. % Li 2 O, wherein:\n a ratio of Li 2 O to R 2 O is greater than 0.5 and less than or equal to 1, wherein R 2 O is the sum (mol. %) of Li 2 O, K 2 O, and Na 2 O in the glass substrate; and \n the glass substrate is substantially free of TiO 2 .
