Zusammenfassung: | A glass composition includes greater than or equal to 50 mol % and less than or equal to 70 mol % SiO2; greater than or equal to 10 mol % and less than or equal to 20 mol % Al2O3; greater than or equal to 1 mol % and less than or equal to 10 mol % B2O3; greater than or equal to 7 mol % and less than or equal to 14 mol % Li2O; greater than 0 mol % and less than or equal to 8 mol % Na2O; greater than 0 mol % and less than or equal to 1 mol % K2O; greater than or equal to 0 mol % and less than or equal to 7 mol % CaO; greater than or equal to 0 mol % and less than or equal to 8 mol % MgO; and greater than or equal to 0 mol % and less than or equal to 8 mol % ZnO. R2O+R′O is less than or equal to 25 mol %, wherein R2O is the sum of Li2O, Na2O, and K2O and R′O is the sum of CaO, MgO, and ZnO. The glass composition includes at least one of NiO+Co3O4+Cr2O3+CuO is greater than or equal to 0.001 mol %, CeO2 is greater than or equal to 0.1 mol %, and TiO2 is greater than or equal to 0.1 mol %. |
