Abstract:
A glass-based article having 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 having a stress profile with a surface compressive stress (CS) and a maximum central tension (CT). The maximum CT is greater than or equal to 50 MPa and less than or equal to 200 MPa and 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 is greater than or equal to 200 MPa and less than or equal to 500 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.
