Abstract: A glass composition includes: greater than or equal to about 70 mol % and less than or equal to about 90 mol % SiO2; greater than or equal to about 2 mol % and less than or equal to about 9 mol % Al2O3; greater than or equal to about 5 mol % and less than or equal to about 15 mol % Li2O; greater than or equal to about 0 mol % and less than or equal to about 10 mol % Y2O3; greater than or equal to about 0 mol % and less than or equal to about 9 mol % Ta2O5; greater than or equal to about 0 mol % and less than or equal to about 10 mol % La2O3; and greater than or equal to about 0.05 mol % and less than or equal to about 1 mol % SnO2. The sum of Y2O3, Ta2O5, and La2O3 may be greater than or equal to about 2 mol % and less than or equal to about 15 mol %.
