Laminated and ion-exchanged strengthened glass laminates
摘要:
A method of making a glass sheet (10) comprises laminating a high CTE core glass (11) to a low CTE clad glass (12) at high temperatures and allowing the laminate (10) to cool creating compressive stress in the clad glass (12), and then ion exchanging the laminate (10) to increase the compressive stress in the outer near surface regions of the clad glass (12). The core glass (11) may include ions that exchange with ion in the clad glass (12) to increase the compressive stress in inner surface regions of the clad glass (12) adjacent to the clad glass/core glass interfaces. The glass laminate (10) may be formed and laminated using a fusion forming and laminating process and fusion formable and ion exchangeable glass compositions.
