Abstract
The invention is directed to a high strength, chemically toughened protective glass article, the glass article having a high damage tolerance threshold of at least 1500 g as measured by the lack of radial cracks when the load is applied to the glass using a Vickers indenter; preferably greater than 2000 g s measured by the lack of initiation of radial cracks when the load is applied to the glass using a Vickers indenter
Claims7
A high strength, chemically toughened protective glass article, said protective glass article having a thickness less than or equal to 2.0 millimeters, a high damage tolerance threshold of at least 6000 g as measured by the lack of the presence of radial cracks when the load is applied to the glass using a Vickers indenter, and a compressive stress greater than 600 MPa.
