Abstract: An article includes a glass, glass-ceramic, or ceramic substrate with at least one surface that has a textured region. The textured region includes a plurality of topographical features that define voids opening towards the surface. The article further includes a coating that comprises a cured silicon oxide (SiOx) material positioned in a pattern on at least a portion of the textured region to fill the voids at least partially. The cured SiOx material planarizes the textured region and modifies surface attributes such as haze, distinctness-of-image (DOI), surface roughness, and abrasion performance. A method is disclosed for planarizing a textured surface by jetting a solution comprising a SiOx material and a solvent in a pattern on a portion of the textured surface. The SiOx solution is cured to form a coating comprising the cured SiOx material.

Abstract: Glass-based substrates are described herein that may be processed by methods including applying a cover article onto a glass-based substrate, submerging the glass-based substrate in an etchant, and maintaining the submersion of the glass-based substrate in the etchant. The glass-based substrate may include a covered surface portion and an exposed surface portion. At least a portion of the covered surface portion may be in direct contact with the cover article. The covered surface portion may not be in contact with the etchant and the exposed surface portion may be in direct contact with the etchant. The etchant may contact the exposed surface portion and the cover article fora time sufficient to etch the exposed surface portion. The cover article may provide a barrier between the etchant and the covered surface portion for the entirety of the submerging.

Abstract: A method for extracting lithium metal ions from glass includes contacting the glass with a molten salt bath for a duration of time, wherein the glass includes lithium and the contacting the glass with the molten salt bath for the duration of time extracts at least 40% of the lithium metal ions from the glass. The method further includes removing residual solids from the molten salt bath, wherein the residual solids include residual glass having a reduced concentration of lithium. The method further includes precipitating lithium metal ions from the molten salt bath to produce a solid precipitated lithium salt and separating the precipitated lithium salt from the molten salt bath.

Abstract: A glass article (and methods for forming the same) includes a glass body having first and second opposing primary surfaces and a thickness defined between the primary surfaces. The glass body includes a compressive stress region that includes: a surface stress of greater than about 900 MPa (compressive), a spike region having a first slope, and a tail region having a second slope. The spike region and the tail region can intersect at a knee region having a stress of greater than about 35 MPa (compressive), wherein the stress at the knee region is defined as the point where the asymptotic extrapolation of the spike region and the tail region intersect. The first slope of the spike region can be steeper than about −30 MPa/μm.

Abstract: Deadfront articles that include a tactile element formed on a first surface of a substrate and a visual element disposed on a second surface of the substrate opposite the first surface. The tactile element is positioned on the first surface of the substrate in a complimentary fashion to the visual element disposed on the second surface of the substrate. The tactile element may include a surface roughness portion having a surface roughness different than the surface roughness of an area bordering the surface roughness portion. The deadfront articles may be incorporated into an automobile interior to provide a visual and haptic display interface for a user.
