Ion exchange for glass strengthening
Web7 nov. 2012 · 1. Introduction. Ion-exchange has been used exactly for one century to modify the surface properties of glass; Schülze in 1913 [] was in fact the first to demonstrate that monovalent cations contained in glass could be exchanged when a soda lime silicate glass was immersed into a bath of molten silver nitrate.During the years, ion-exchange … Web16 mrt. 2016 · Glasses can be chemically strengthened through the ion exchange process, wherein smaller ions in the glass (e.g., Na+) are replaced by larger ions from a salt bath (e.g., K+). This develops a compressive stress (CS) on the glass surface, which, in turn, improves the damage resistance of the glass. The magnitude and depth of the …
