    Abstract: A method for fabricating a high-density array of holes in glass comprises providing a glass sheet having a front surface and irradiating the glass sheet with a laser beam so as to produce open holes extending into the glass sheet from the front surface of the glass sheet. The beam creates thermally induced residual stress within the glass around the holes, and after irradiating, the glass sheet is annealed to eliminate or reduce thermal stress caused by the step of irradiating. The glass sheet is then etched to produce the final hole size. Preferably, the glass sheet is also annealed before the step of irradiating, at sufficiently high temperature for a sufficient time to render the glass sheet dimensionally stable during the step of annealing after irradiating.

  • Patent number: 9051199
    Abstract: A process for making soda-lime glass includes calcining calcium carbonate in solid phase and at elevated temperature to form calcium oxide in solid phase and carbon dioxide gas. Sodium silicate glass is formed and refined separately in liquid phase. The solid phase calcium oxide is dissolved in the refined liquid phase sodium silicate glass to form a soda-lime glass melt. Formation of sodium silicate glass as an intermediate product before mixing with calcium oxide has the advantage of promoting release of gaseous reaction products from the sodium silicate glass during the refining step due at least in part to the relatively low viscosity of the sodium silicate glass. One or more steps in the process can be carried out under reduced pressure to promote release of gases and to reduce bubble formation.

    Abstract: A cover glass element can extend to the edges of an electronic device while maintaining the optical flatness and thickness needed for the cover glass. A first glass sheet with the desired thickness and flatness can be thermally bonded to a second glass sheet machined to include an opening to be received by the edges of the electronic device. The resulting three-dimensional cover element forms a uni-body frame that is significantly stiffer than a single sheet of glass, and the larger surface area of the edge provides for enhances pressure distribution, particularly after chemical strengthening, thus enhancing the durability of the electronic device. Further, the thermal bonding process uses lower temperatures than processes such as slumping or pressing, which could potentially affect the flatness and optical clarity of the original sheet glass.

    Abstract: In one embodiment, a method of forming a glass container may include forming a glass container comprising a sidewall at least partially enclosing an interior volume. At least a portion of the interior surface of the sidewall may have an interior surface layer with a persistent layer heterogeneity relative to a midpoint of the sidewall. The interior surface layer of the glass container may be removed from the interior surface of the sidewall such that a modified interior surface of the sidewall has an interior region extending from about 10 nm below the modified interior surface into a thickness of the sidewall. The interior region may have a persistent layer homogeneity relative to the midpoint of the sidewall such that the modified interior surface is resistant to delamination.

  • Publication number: 20140147624
    Abstract: Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.

  • Publication number: 20140116091
    Abstract: A method for fabricating a high-density array of holes in glass comprises providing a glass sheet having a front surface and irradiating the glass sheet with a laser beam so as to produce open holes extending into the glass sheet from the front surface of the glass sheet. The beam creates thermally induced residual stress within the glass around the holes, and after irradiating, the glass sheet is annealed to eliminate or reduce thermal stress caused by the step of irradiating. The glass sheet is then etched to produce the final hole size. Preferably, the glass sheet is also annealed before the step of irradiating, at sufficiently high temperature for a sufficient time to render the glass sheet dimensionally stable during the step of annealing after irradiating.

  • Publication number: 20140120311
    Abstract: A thermo-electric method for texturing a glass surface including, for example, simultaneously heating a glass substrate to a temperature less than its glass transition temperature and applying a bias across the glass substrate using a template electrode. The applied bias at the processing temperature induces localized ion migration within the glass, which results in the formation in the glass surface of a negative topographical image of the pattern formed in the electrode.

  • Publication number: 20140109617
    Abstract: Systems and methods for processing lead-containing glass are generally described. In certain embodiments, at least a portion of the lead within the bulk of the lead-containing glass is removed from the lead-containing glass and transferred to a liquid leaching medium. Removal of lead from the bulk of the lead-containing glass, as opposed to the surface and areas closely adjacent to the surface of the lead-containing glass, can allow for the production of recycled glass that includes substantially no lead within its boundaries.
