Abstract: Methods of making ion-exchanged glass articles including exposing the glass articles to a molten salt including 2 wt % to 10 wt % of an inorganic non-hydroxide salt sufficient to provide a pH from 9 to 12 when 5 grams of the inorganic non-hydroxide salt is dissolved in 100 grams of distilled water. The high-pH molten salts comprising the inorganic non-hydroxide salt can ion-exchange thin glass articles to have desirable mechanical performance without the use of a post-ion-exchange etching step. In some embodiments, the molten salt can include less than 1 wt % sodium nitrate (NaNO3).

Abstract: Ion-exchanged alkali aluminosilicate glass articles with a ratio of peak compressive stress value to Young's modulus value of 15 or more. The glass articles may include Al2O3 mol %+RO mol %≥17 mol %, where RO mol %=MgO mol %+CaO mol %, and be substantially free of ZnO, SrO, BaO, B2O3, P2O5, Li2O, and K2O. The glass articles may have a peak compressive stress value in a range of 500 MPa to 1300 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.

Abstract: Aluminosilicate or aluminoborosilicate glass compositions and products comprising the same are provided. Such glass compositions are substantially alkali-free and include oxides of alkaline earth metals. The glass composition may include a low concentration of boron oxide. The glass compositions exhibit desirable physical properties and chemical properties, for example, improved annealing point (e.g., higher than 775° C.), improved elastic modulus, lowered stress optical coefficient (SOC), and desirable liquidus viscosity. The glass compositions are suitable for use as substrates in flat panel display devices such as active matrix liquid crystal displays (AMLCDs) with ultra-high resolution.

Abstract: Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a first central surface area recessed from a first major surface by a first distance and a second central surface area. A second major surface comprises the second central surface area. A blunted edge extends around an entire periphery of the foldable substrate. The blunted edge comprising a first blunted surface area where the blunted edge meets the first major surface and a second blunted surface area where the blunted edge meets the second major surface. Methods comprise laminating the foldable substrate with support layers before removing a peripheral portion of an initial edge of the foldable substrate to form an intermediate edge. The intermediate edge is contacted with an etchant to form the blunted edge. Methods further comprise removing the support layers from the foldable substrate.

Abstract: An edge surface includes a first peripheral surface extending between a first major surface and an outer peripheral surface of a substrate. The first peripheral surface includes a first depth and a first width. In aspects, the first depth is from about 4 micrometers to about 12 micrometers, and the first width is from about 30 micrometers to about 50 micrometers. In aspects, the first depth is from about 14 micrometers to about 24 micrometers, and the first width is from about 40 micrometers to about 60 micrometers. In aspects, a ratio of the first depth to a substrate thickness is from about 0.2 to about 0.4, a ratio of the first width to the substrate thickness is from about 1 to about 1.55, and a ratio of the first width to the first depth is from about 2 to about 8.

Abstract: Methods of forming a foldable substrate comprise providing a glass-based substrate comprising a first compressive stress region extending to an existing first depth of compression from an existing first major surface. Methods comprise contacting the existing first major surface with a solution to remove an outer compressive layer of the first compressive stress region to form a new first major surface. The outer compressive layer ranges from about 0.05 micrometers to about 5 micrometers. The solution can comprise a first temperature in a range from about 60° C. to about 120° C. The solution can comprise an alkaline solution comprising about 10 wt % or more of a hydroxide-containing base. In aspects, the method can comprise one or more of: attaching an adhesive layer to the new first major surface, attaching a display device to the new first major surface, or disposing a coating over the new first major surface.
