Abstract

See full text

A glass composition comprises: 50.0 mol % to 70.0 mol % SiO2; 10.0 mol % to 25.0 mol % Al2O3; 0.0 mol % to 5.0 mol % P2O3; 0.0 mol % to 10.0 mol % B2O3; 5.0 mol % to 15.0 mol % Li2O; 1.0 mol % to 15.0 mol % Na2O; and 0.0 mol % to 1.0 mol % K2O. The sum of all alkali oxides, R2O, present in the glass composition may be in the range from greater than or equal to 11.0 mol % to less than or equal to 23.0 mol %. The sum of Al2O3 and R2O present in the glass composition may be in the range from greater than or equal to 26.0 mol % to less than or equal to 40.0 mol %. The glass composition may satisfy the relationship −0.1<(Al2O3−(R2O+RO))/Li2O<0.3.
