Abstract:
A glass article includes: from 60 mol % to 80 mol % SiO2; from 5 mol % a to 25 mol % Al2O3; from 0.25 mol % to 10 mol % MgO; from 0.25 mol % to 10 mol % Na2O; from 0 mol % to 2 mol % Li2O; from 0 mol % to 9 mol % La2O3; and from 0 mol % to 9 mol % Y2O3. La2O3+Y2O3 is from 2 mol % to 9 mol %. (La2O3+Y2O3)/(R2O+RO) is from 0.1 to 2, R2O being the sum of Na2O, Li2O, and K2O, and RO being the sum of MgO, CaO, SrO, and BaO.
