Problems solved by technology

[0010] Unfortunately, quality control of glasses with peak stress distributions is lacking because the distribution cannot be adequately characterized in a non-destructive manner
This deficiency makes the manufacture of chemically strengthened Li-containing glasses difficult and delays the use of chemically strengthened Li-containing glasses in the market

Abstract

Methods for characterizing ion-exchanged chemically strengthened glasses containing lithium are disclosed. The method enables quality control of the stress distribution in chemically strengthened Li-containing glasses with surface stress spikes generated in potassium-containing salts, especially salts with both potassium and sodium. The method enables measurements of surface compression and peak depth, and their contribution to central tension, and compression at the base of the peak and total central tension, as well as calculation of stress at the knee where the peak of the stress profile intersects the deep region. The measurements are for commercially important distributions that are nearly parabolic in shape throughout most of the interior of the substrate except for the peak.

Description

[0001] Cross References to Related Applications [0002] This application is related to US Provisional Patent Application Serial No. 62 / 219,949, filed September 17, 2015, which is incorporated herein by reference. technical field [0003] The present disclosure relates to chemically strengthened glasses, and in particular, to methods of characterizing chemically strengthened glasses containing lithium. [0004] technical background [0005] Chemically strengthened glass is glass that has been chemically modified to improve at least one strength-related property such as hardness, fracture resistance, and the like. Chemically strengthened glass has been found to be particularly suitable for use as cover glass for display-based electronics, especially handheld devices such as smartphones and tablets. [0006] In one method, chemical strengthening is achieved through an ion exchange process whereby ions in the glass matrix are replaced by externally introduced ions, such as from...
