Crack Initiation Tendency of Chemically Strengthened Glasses

The relationship between crack initiation tendency before chemical strengthening and fracture strength of chemically strengthened glass was investigated. Four kinds of glass compositions were used in this study: soda‐lime silicate (SLS), aluminosilicate (ALS‐1, ALS‐2), and aluminoborosilicate (ALBS)...

Summary:The relationship between crack initiation tendency before chemical strengthening and fracture strength of chemically strengthened glass was investigated. Four kinds of glass compositions were used in this study: soda‐lime silicate (SLS), aluminosilicate (ALS‐1, ALS‐2), and aluminoborosilicate (ALBS) glasses. The fracture strength of sheet glass was measured by the four‐point bending test, the ring‐on‐ring test, the ball drop test, and the predamaged four‐point bending test. ALBS glass, which has the lowest crack formation probability before chemical strengthening, is more damage tolerant than other glasses, and one of the best candidates for chemical strengthening.
