SALT BATH COMPOSITIONS, SALT BATH SYSTEMS, AND PROCESSES FOR STRENGTHENING GLASS ARTICLES

Abstract:

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.
