Abstract: Described herein are various antimicrobial glass articles that have improved resistance to discoloration when exposed to harsh conditions. The improved antimicrobial glass articles described herein generally include a glass substrate that has a low concentration of nonbridging oxygen atoms, a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth, such that the glass article experiences little-to-no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.

Abstract: A method of removing residue containing an insoluble lithium phosphate compound from a surface includes soaking the surface in a cleaning aqueous solution having a pH less than 5 for a select time period, whereby the insoluble lithium phosphate compound is converted into soluble lithium hydrogen phosphate and the soluble lithium hydrogen phosphate is dissolved in the cleaning aqueous solution. The method includes rinsing the surface with deionized water. The surface is substantially free of the insoluble lithium phosphate compound after the rinsing.

Abstract: Methods for regenerating poisoned salt bath comprising providing a salt bath comprising at least one of KNO3 and NaNO3, providing an ion-exchangeable substrate comprising lithium cations, contacting at least a portion of the ion-exchangeable substrate with the salt bath, whereby lithium cations in the salt bath diffuse from the ion-exchangeable substrate and are dissolved in the salt bath, and selectively precipitating dissolved lithium cations from the salt bath using phosphate salt. The methods further include preventing or reducing the formation of surface defects in the ion-exchangeable substrate by preventing or reducing the formation of crystals on the surface of the ion-exchangeable substrate upon removal from the salt bath.

Abstract: A method of forming a glass substrate includes providing a glass substrate having alumina, translating a pulsed laser beam on the glass substrate to form one or more pilot holes, contacting the glass substrate with an etching solution, and providing agitation. The etching solution has a pH from about 0 to about 2.0, and an etch rate is less than about 3 μm/min. A glass substrate is disclosed having a first surface and a second surface opposite the first surface in a thickness direction, and at least one hole penetrating the first surface, wherein the at least one hole has been etched by an etching solution. A greatest distance d1 between (1) a first plane that contacts the first surface in regions that do not have the at least one hole or a deviation in a thickness of the substrate surrounding the at least one hole and (2) a surface of the deviation recessed from the first plane is less than or equal to about 0.2 μm.

Abstract: Methods of recovering lithium from glass include crushing the glass to produce glass particles and contacting the glass particles with an aqueous leaching solution at a leaching temperature greater than ambient temperature and less than the boiling temperature of the aqueous leaching solution to produce a leachate slurry. The glass particles include lithium. The aqueous leaching solution includes sulfuric acid in water or sodium hydroxide in water. Contacting the glass particles with the aqueous leaching solution leaches greater than or equal to about 50% of the lithium out of the glass particles. The methods further comprise separating the leachate slurry to produce a solid residue and a leachate, the leachate comprising the lithium leached from the glass particles. The method further include recovering the lithium from the leachate through precipitation.
