Abstract
Methods of manufacturing a glass-based article includes exposing a glass-based substrate having a lithium aluminosilicate composition to an ion exchange treatment to form the glass-based article. The ion exchange treatment including a molten salt bath having a concentration of a sodium salt in a range from 8 mol % to 100 mol %. The glass-based article includes sodium having a non-zero varying concentration extending from a surface of the glass-based article to a depth of the glass-based article The glass-based article has compressive stress layer extending from the surface to a spike depth of layer from 4 micrometers to 8 micrometers. The glass-based article includes a molar ratio of potassium oxide (KO) to sodium oxide (NaO) averaged over a distance from the surface to a depth of 0.4 micrometers that is greater than or equal to 0 and less than or equal to 1.8.
