摘要： A method for producing a structured glass disk is provided that includes the steps of: providing a glass disk having a thickness of at most 400 μm; directing and focusing a laser beam onto the glass disk such that the laser beam produces an elongated focus within the glass disk with an intensity sufficient to produce damage within the glass disk along the elongated focus; moving the laser beam and the glass disk relative to one another to insert damage zones along a ring-shaped path so that a workpiece is defined in the glass disk with the ring-shaped path encompassing the workpiece and with the workpiece remaining connected to the glass disc; exposing the glass disk to an etchant so that the etchant intrudes into the damage zones; and chemically toughening the glass disk with the workpiece.

The at least one edge has at least one chamfer with a chamfer width (A) and a chamfer height (B). The chamfer has a ratio of chamfer width/chamfer height (A/B) of between 1.5-20 and the chamfer has a ratio of chamfer width/glass thickness (A/t) of at least 0.5.

摘要： A thin glass article is provided that has a first face, a second face, one or more edges joining the first and second faces, and a thickness between the first and second faces, where the faces and the one or more edges together form an outer surface of the thin glass article. The thin glass article has an ion-exchanged surface layer on its outer surface. The ion-exchanged surface layer is non-uniform, wherein the non-uniform ion-exchanged surface layer has an associated compressive surface stress which varies between a minimum and a maximum value over the outer surface and/or a depth of layer which varies between a minimum and a maximum value over the outer surface. A method for producing a thin glass article and a use of a thin glass article are also provided.

摘要： A method for chemical toughening a thin glass article with a thickness of at most 0.07 mm is provided. The method includes immersing the glass article into a bath of molten salt having a certain toughening temperature for a certain toughening time to form a toughened glass article; lifting the toughened glass article out of the bath of molten salt; post-toughening dwelling the toughened glass article for a certain dwelling time at a dwelling temperature that is higher than a melting point of the bath of molten salt and lower than a transition temperature (Tg) of the toughened glass article; and cooling and cleaning the toughened glass article.

摘要： An ultrathin chemically toughened and subsequently etched glass article is provided. The article has a thickness of less than or equal to 0.4 mm and a breakage height (given in mm) of more than 200 multiplied by the thickness (t given in mm)). Further, the article has a breakage bending radius (given in mm) of less than 100000 multiplied by the thickness (t given in mm) and divided by a surface compressive stress (in MPa) measured at a first surface.

摘要： A method for producing an ultrathin chemically toughened glass article is provided that includes: providing an ultrathin glass sheet with a first surface and a second surface joined by at least one edge, having a thickness between the first and the second surface, chemically toughening the ultrathin glass sheet to produce an ultrathin toughened glass article. The method includes applying an edge pre-treatment to the at least one edge, preferably all edges, of the ultrathin glass sheet prior to the chemical toughening in order to reduce and/or blunt edge defects and to increase resistance to breakage of the ultrathin glass sheet during the chemical toughening.

摘要： A shaped glass article is provided that is ultrathin, has two surfaces and one or more edges joining the two surfaces, and a thickness between the two surfaces. The shaped ultrathin glass article has at least one curved area with a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied. A method for producing a shaped glass article is also provided that includes providing an ultrathin glass with two surfaces and one or more edges joining the two surfaces, having a thickness between the two surfaces and shaping the ultrathin glass to a shaped ultrathin glass article by forming at least one curved area having a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied to the shaped ultrathin glass article.
