Mutual diffusivity, network dilation, and salt bath poisoning effects in ion-exchanged glass

Molecular dynamics simulations of ion-exchanged glass

“…We specifically choose alkali aluminosilicates for this study since the structural and topological environment around aluminum allows for high alkali mobility while maintaining a rigid glass network [29][30][31][32][33][34][35]. Hence, alkali aluminosilicate glasses are the preferred choice for commercial chemically strengthened glass products.…”

Mechanical–Structural Investigation of Chemical Strengthening Aluminosilicate Glass through Introducing Phosphorus Pentoxide

“…Because of the increasing demand for high strength and damage resistance glasses, new methods to enhance CS, DOL, and hardness have become a focus of research. Up to now, many investigations on the strengthening process, molten salt, and glass composition have been carried out (Nordberg et al, 1964;Anna and Mauro, 2013;Svenson et al, 2014;Sglavo, 2015). However, the treatment of aluminosilicate glasses was limited in chemical strengthening due to the relatively small DOL.…”

A study on ion‐exchanged, soda‐lime glass’s residual stress relationship with K+/Na+ concentration

“…The experimental work of Tsutsumi et al on the swelling of Na + ‐K + exchanged SLG waveguides suggested a relative constant value of B for KNO 3 bath temperatures in the range 350°C‐440°C. Similarly, the experimental work conducted by Fu and Mauro showed that in SLG, B marginally increased with K 2 O diffusion. It should be noted that Fu et al's calculations used core glass values for E and ν to estimate B .…”

“…Sinton et al soaked SLG into a KNO 3 melt at 450°C and reported D = 0.07 µm 2 /min form K + concentration profiles. Fu and Mauro immersed SLG samples in 100% KNO 3 salt bath at 410°C for 8 hours, at 370°C for 16 hours, and at 450°C for 4 hours and measured D for each condition ( D = 5.3 × 10 −3 µm 2 /min at 370°C, D = 0.027 µm 2 /min at 410°C, and D = 0.082 µm 2 /min at 450°C). Gy provided normalized K 2 O concentration profiles for SLG soaked for 72 hours in KNO 3 salt bath at various temperatures (420°C, 460°C, and 490°C).…”
