Abstract
Embodiments of glass compositions, glass articles and chemically strengthened glass articles are disclosed. In one or more embodiments, the glass composition comprises LiO, greater than about 0.9 mol % BO, AlOin an amount greater than or equal to 10 mol %, and from about 60 mol % to about 80 mol % SiO. Embodiments of the chemically strengthened glass article include a first major surface and an opposing second major surface defining a thickness t, a compressive stress layer extending from the first major surface to a depth of compression greater than about 0.12 t, a maximum compressive stress of about 200 MPa or greater, and a Knoop Lateral Cracking Scratch Threshold greater than about 6 N, as measured on either one of the first major surface and the second major surface. Methods for forming such chemically strengthened glass articles are also disclosed.
