Abstract:
A glass pharmaceutical package having a glass composition of 68.00 mol % to 81.00 mol % SiO2, from 4.00 mol % to 11.00 mol % Al2O3, from 0.10 mol % to 16.00 mol % Li2O, from 0.10 mol % to 12.00 mol % Na2O, from 0.00 mol % to 5.00 mol % K2O, from 0.10 mol % to 8.00 mol % MgO, from 0.10 mol % to 5.00 mol % CaO, from 0.00 mol % to 0.20 mol % fining agent. The glass pharmaceutical package is delamination resistant, and has class 1 or class 2 chemical durability in acid, base, and water. The glass pharmaceutical package may have a surface compressive stress of at least 350 MPa.
