Publication number: 20220348496Abstract: Methods for regenerating a salt bath composition include heating the salt bath composition to an ion exchange temperature to form a molten salt bath. The methods may further include contacting at least a portion of an ion-exchangeable article that includes lithium oxide (Li2O) with the molten salt bath. Lithium cations may diffuse from the ion-exchangeable article and into the molten salt bath. Additionally, the methods may include adding a first phosphate salt to the molten salt bath. A lithium phosphate salt that includes at least a portion of the lithium cations may be formed and precipitate from the molten salt bath. Furthermore, the methods may include adding a multivalent salt that includes a multivalent metal cation to the molten salt bath. A second phosphate salt that includes the multivalent metal cation may be formed and precipitate from the molten salt bath.Type: ApplicationFiled: September 10, 2020Publication date: November 3, 2022Inventors: David Eugene Baker, Albert Joseph Fahey, Qiang Fu, Yuhui Jin, Wei Sun, Ljerka Ukrainczyk, Shelby Kerin Wilson

Patent number: 10898933Abstract: Described herein are glass substrates having oleophobic surfaces that are substantially free of features that form a reentrant geometry. The surfaces can include a plurality of gas-trapping features, extending from the surface to a depth below the surface, that are substantially isolated from each other. The gas-trapping features are capable of trapping gas below any droplets that are contacted with the surface so as to prevent wetting of the surface by the droplets.Type: GrantFiled: May 30, 2013Date of Patent: January 26, 2021Assignee: CORNING INCORPORATEDInventors: Adra Smith Baca, David Eugene Baker, Prantik Mazumder, Mark Alejandro Quesada, Wageesha Senaratne
