THIN GLASS WITH IMPROVED BENDABILITY AND CHEMICAL TOUGHENABILITY

THIN GLASS WITH IMPROVED BENDABILITY AND CHEMICAL TOUGHENABILITY

A chemically toughenable or toughened glass is provided. The glass has, before chemical toughening, a thickness of at most 500 μm. The glass, after chemical toughening, has a BACT (bendability and chemical toughenability) calculated as BACT=(CS*DoL)/(t*E) which is greater than 0.00050 and/or a NS (n...

Zusammenfassung:A chemically toughenable or toughened glass is provided. The glass has, before chemical toughening, a thickness of at most 500 μm. The glass, after chemical toughening, has a BACT (bendability and chemical toughenability) calculated as BACT=(CS*DoL)/(t*E) which is greater than 0.00050 and/or a NS (normalized stiffness) calculated as NS=CS/E which is greater than 0.0085, where CS is a compressive stress in MPa measured at one side of the glass after chemical toughening, DoL is a total depth of all ion-exchanged layers in μm on one side of the glass after chemical toughening, t is a thickness of the glass in μm after chemical toughening, and E is a E-modulus in MPa after chemical toughening.
