Glass-based articles with a concentration gradient of metal oxide

摘要

A glass-based article, featuring:a first area and a second area opposite the first area, defining a thickness (t) (mm); anda concentration of a metal oxide which varies both from zero and along a thickness range of approximately 0.t to 0.3;t;a surface pressure voltage of approximately 300 MPa or more; anda CT area with a maximum CT of less than 71,5/(t).
