Abstract: The methods generally include contacting an alkali-containing glass article having a first alkali metal cation with a molten salt bath including from 0.1 wt. % to 3 wt. % nanoparticles and at least one alkali metal salt having a second alkali metal cation that has an atomic radius larger than an atomic radius of the first alkali metal cation. The nanoparticles may include at least one of metalloid oxide nanoparticles and metal oxide nanoparticles. The methods also include maintaining contact of the glass article with the molten salt bath to allow the first alkali metal cations to be exchanged with the second alkali metal cations of the molten salt bath. Further, the methods may include removing the glass article from contact with the molten salt bath to produce a strengthened glass article. A Surface Hydrolytic Resistance titration volume of the strengthened glass article may be less than 1.5 mL.

Abstract: Embodiments of the present disclosure are directed to salt bath systems for strengthening glass articles including a salt bath tank defining a first interior volume enclosed by at least one sidewall; a salt bath composition including an alkali metal salt positioned within the first interior volume; a containment device defining a second interior volume enclosed by at least one sidewall and including a regeneration medium positioned within the second interior volume; and a circulation device positioned proximate to an inlet of the containment device, wherein the circulation device is operable to circulate the salt bath composition through the containment device. Methods for regenerating a molten salt are also disclosed.

Abstract: According to one embodiment, a glass article may include SiO2, Al2O3, Li2O and Na2O. The glass article may have a softening point less than or equal to about 810° C. The glass article may also have a high temperature CTE less than or equal to about 27×10−6/° C. The glass article may also be ion exchangeable such that the glass has a compressive stress greater than or equal to about 600 MPa and a depth of layer greater than or equal to about 25 μm after ion exchange in a salt bath comprising KNO3 at a temperature in a range from about 390° C. to about 450° C. for less than or equal to approximately 15 hours.

Abstract: A sealed pharmaceutical container includes a shoulder, a neck extending from the shoulder, and a flange extending from the neck. The flange includes an inclined sealing surface defining an opening in the sealed pharmaceutical container. The sealed pharmaceutical container also includes a sealing assembly including a stopper extending over the sealing surface of the flange and a cap securing the stopper to the flange. The stopper has a glass transition temperature (Tg) that is greater than or equal to −70° C. and less than or equal to −45° C. The sealing assembly maintains a helium leakage rate of the sealed pharmaceutical container of less than or equal to 1.4×10−6 cm3/s as the sealed pharmaceutical container is cooled to a temperature of less than or equal to −45° C.
