Abstract:
A glass composition includes: greater than or equal to 24 mol % and less than or equal to 60 mol % SiO2; greater than or equal to 23 mol % and less than or equal to 35 mol % Al2O3; greater than or equal to 3.5 mol % and less than or equal to 35 mol % B2O3; greater than 0 mol % and less than or equal to 20 mol % Li2O; greater than or equal to 0 mol % and less than or equal to 10 mol % Na2O; and greater than or equal to 0 mol % and less than or equal to 3 mol % K2O. The sum of Li2O, Na2O, and K2O (i.e., R2O) in the glass composition may be greater than or equal to 12 mol % and less than or equal to 20 mol %.
