摘要：
A glass composition includes: from 55.0 mol % to 70.0 mol % SiO2; from 12.0 mol % to 20.0 mol % Al2O3; from 5.0 mol % to 15.0 mol % Li2O; and from 4.0 mol % to 15.0 mol % Na2O. The glass composition has the following relationships −8.00 mol %≤R2O+RO−Al2O3−B2O3−P2O5≤−1.75 mol %, 9.00≤(SiO2+Al2O3+Li2O)/Na2O, and (Li2O+Al2O3+P2O5)/(Na2O+B2O3)≤3.50. The glass composition may be used in a glass article or a consumer electronic product.
