Abstract:
Glasses having a high degree of resistance to damage cause by abrasion, scratching, indentation, and the like are disclosed. In embodiments, the glasses may include at least 50 mol % SiO2; 9 mol % to 22 mol % Al2O3; Na2O; Li2O; at least 10 mol % R2O, wherein R2O is the sum of alkali metal oxides in the glass; 2.7 mol % to 4.5 mol % B2O3; and greater than 0.1 mol % of MgO+ZnO, wherein (B2O3—(R2O—Al2O3)) is greater than or equal to 3.
