Effect of Edge Quality on the Strength Obtained by Ion-exchanging

J . Zuidema, F.A.Veer

Ion exchanging is one of the methods used to pre-stress glass. Although the process has been known for many years it is not very popular due to the fact that it is not suitable for continuous line fabrication. The advantages are that it is suitable for curved glass and glass tubes while also allowing for more control over the pre-stress level than is possible with thermal toughening techniques. For the engineer who designs in glass a problem is the lack of reliable strength information. Although very high strengths are claimed for ion-exchanged glass, the measured values have a high spread and thus the reliability is low.

To resolve this research has been done with the purpose of investigating the reasons for the large scatter in data.
