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.
