Arun Varshneya: High-Strength, Large Case-Depth Chemically Strengthened Glass

Published on June 25th, 2009 | By: pwray@ceramics.org

From PACRIM8, this lecture discusses recent advances in improving the
strength of glass. In particular, Alfred University professor Arun
K. Varshneya explains the process of using NaNO3 + KNO3 salt baths to
strengthen high-glass-transition-temperature aluminosilicate glass to give the material high resistance to fracture upon flexing from projectile impact. Varshneya also discusses applications such as transparent armor and other new market opportunities for strengthened glass. 33 minutes.

 

Much of the same information found in this lecture can also be found in a Glass Researcher article in the May 2009 issue of the Bulletin, written by Varshneya and Ian M. Spinelli.
