Stress Relaxation of Ion Exchanged Float Aluminosilicate Glass at Different Temperature

Article Preview

Abstract:

The effect of the annealing temperature (390°C, 410 °Cand 430°C) on the stress relaxation of air side and tin side of ion exchanged glasses was investigated. The annealing time dependence of stress at different temperature can be well fitted by a second order exponential function. The stress relaxation rate on tin side is larger than air side at the ion exchange temperature (410°C) or below (390°C) but smaller above the ion exchange temperature (430°C). The depths of stress layer (DOL) of all ion exchanged glasses increase with the increasing of annealing time and the DOL on air side is always larger than tin side. These provide useful information for subsequent treatment of ion exchanged glasses.
