Abstract
In aspects, a concentration of lithium oxide at a surface is greater than a concentration of lithium oxide at a midpoint by from about 0.2 mol % to about 2 mol %. In aspects, a concentration of lithium oxide at a surface is from about 0.2 mol % to about 2 mol %. In aspects, a total concentration of potassium oxide, rubidium oxide, cesium oxide, and francium oxide at a surface is from about 5 mol % to about 15 mol %. In aspects, a ratio of the total concentration of potassium oxide, rubidium oxide, cesium oxide, and francium oxide at a surface to a concentration of lithium oxide at the surface is from about 1 to about 20. Methods include immersing a substrate in a molten salt bath at 380° C. or more for from about 1 minute to about 10 minutes or for from about 3 minutes to about 2 hours.
