  • Patent number: 11952312
    Abstract: Glass compositions are provided with low Young's modulus and compatibility with slot drawing techniques, due at least in part to liquidus viscosity and liquidus temperature. When ion-exchanged the resulting glass articles are capable of exhibiting a ratio of a peak compressive stress value in MPa to a Young's modulus value in GPa of 13.0 or more. The glass articles may have a peak compressive stress value in a range of 850 MPa to 1400 MPa. The glass articles are suitable for various high-strength applications, including cover glass applications that experience significant bending stresses during use, for example, cover glasses for flexible displays.

  • Patent number: 11926552
    Abstract: A glass substrate comprises: a first position, wherein a tensile stress of the glass substrate is insufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate; and a second position, wherein the glass substrate is bent relative to the first position, and wherein the tensile stress of the glass substrate is sufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate. The glass substrate can include a first surface and a second surface. In the first position, the first surface and the second surface of the glass substrate can be planar. In the second position, the first surface and the second surface of the glass substrate can be planar. The small pieces can be generally cubic. In the second position, the glass substrate can be bent uniaxially along a bend axis of the glass substrate.

  • Publication number: 20240010550
    Abstract: A coated glass article and of a system and method for forming a coated glass article are provided. The process includes applying a first coating precursor material to the first surface of the glass article and supporting the glass article via a gas bearing. The process includes heating the glass article and the coating precursor material to above a glass transition temperature of the glass article while the glass article is supported by the gas bearing such that during heating, a property of the first coating precursor material changes forming a coating layer on the first surface of the glass article from the first precursor material. The high temperature and/or non-contact coating formation may form a coating layer with one or more new physical properties, such as a deep diffusion layer within the glass, and may form highly consistent coatings on multiple sides of the glass.
