Embodiments described herein are directed to compositions, systems, and processes for strengthening glass articles, which also minimize the concentration of decomposition products in the molten salt baths used in ion exchange processes to extend salt bath life and maintain the chemical durability of strengthened glass articles over time. The salt bath compositions may generally include from 90 wt. % to 99.9 wt. % of one or more alkali or metal salts and from 0.1 wt. % to 10 wt. % of silicic acid aggregates based on the total weight of the salt bath composition.

Salt bath compositions, salt bath systems, and processes for strengthening glass articles

A method for processing a transparent workpiece includes directing a pulsed laser beam into the transparent workpiece such that a portion of the pulsed laser beam directed into the transparent workpiece generates an induced absorption within the transparent workpiece, thereby forming a damage line within the transparent workpiece, and the portion of the pulsed laser beam directed into the transparent workpiece includes a wavelength &#x3bb;, a spot size w, and a Rayleigh range Zthat is greater than where Fis a dimensionless divergence factor comprising a value of 10 or greater. Further, the method for processing the transparent workpiece includes etching the transparent workpiece with an etching vapor to remove at least a portion of the transparent workpiece along the damage line, thereby forming an aperture extending through the at least a portion of the thickness of the transparent workpiece.

Methods for laser processing transparent workpieces using pulsed laser beam focal lines and vapor etching

Described herein are aqueous acidic glass etching solutions or media comprising HF and HSO, wherein HF is present in concentrations not exceeding about 1.3M. The etching solutions are used to treat glass articles such as thin glass sheets at above-ambient temperatures to etch slight thicknesses of surface glass therefrom, the etching solutions exhibiting improved stability against dissolved glass precipitation and rapid glass removal rates at slightly elevated temperatures.

Media and methods for etching glass

Disclosed are controlled chemical etching processes used to modify the geometry of surface flaws in thin glass substrates and glass substrate assemblies formed therefrom, and in particular glass substrates suitable for the manufacture of active matrix displays that are essentially free of alkali metal oxides such as NaO, KO and LiO.

Surface flaw modification for strengthening of glass articles

Impact-damage-resistant glass sheet comprising at least one chemically etched surface in combination with a tempering surface compression layer, the glass sheet exhibiting a high standardized ball drop failure height and a high flexural modulus of rupture strength, useful to provide damage-resistant glass cover sheets for consumer electronic video display devices, is provided by subjecting thin glass sheet to a combination of a surface tempering treatment and a surface etching treatment that improves strength while maintaining the optical glass sheet properties required for video display applications.

Impact-damage-resistant glass sheet

A glass article having an anti-glare surface. The anti-glare surface has a distinctness-of-reflected image of less than 95, and a haze of less than or equal to 50%. In one embodiment, the glass article further includes a smudge-resistant surface disposed on the anti-glare surface. Methods of making the glass article and anti-glare surface are also described.
