  • Patent number: 12116311
    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 about 0.7·t up to t, comprise a tangent with a slope having an absolute value greater than about 0.1 MPa/micrometer, 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) and a maximum central tension in the range from about 80 MPa to about 100 MPa. In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a value at a point between the first surface and the second surface and increases from the value to the second surface. The concentration of the metal oxide may be about 0.

  • Publication number: 20240279108
    Abstract: A group of glass compositions in the Li2O—Al2O3—SiO2—B2O3 family that can be chemically strengthened in single or multiple ion exchange baths containing at least one of NaNO3 and KNO3 for a short time (2-4 hours) to develop a deep depth of layer (DOL). In some instances, the DOL is at least 70 ?m; in others, at least about 100 ?m. The ion exchanged glasses have a high damage resistance (indentation fracture toughness ranging form greater than 10 kgf to greater than 50 kgf) that is better than or at least comparable to that of sodium aluminosilicate glasses.

  • Patent number: 11970421
    Abstract: Glass articles including one or more 3D printed surface features attached to a surface of a substrate at a contact interface between the 3D printed surface feature and the surface. The 3D printed surface feature(s) include a glass or a glass-ceramic, a compressive stress region at an exterior perimeter surface of the 3D printed surface feature(s), and a central tension region interior of the compressive stress region. The 3D printed surface feature(s) may be formed of a contiguous preformed material 3D printed on a surface of a substrate. The compressive stress region of a 3D printed surface feature may be formed using an ion-exchange process.
