Abstract
A glass-based article includes an amorphous phase and a crystalline phase, and a first surface and a second surface opposing the first surface thereby defining a thickness (t) of the glass-based article. The glass-based article has a stress profile with a surface compressive stress (CS) and a maximum central tension (CT). The maximum CT is greater than or equal to 80 MPa and less than or equal to 95 MPa, and the maximum CT is positioned within the glass-based article at a range from greater than or equal to 0.4·t and less than or equal to 0.6·t. The surface CS of the glass-based article is greater than or equal to 200 MPa; and a depth of compression (DOC) is from greater than or equal to 0.14·t and less than or equal to 0.25·t.
