Abstract

A glass for chemical strengthening contains, in mole percentage on an oxide basis, 58 to 80% of SiO, 13 to 18% of AlO, 0 to 5% of BO, 0.5 to 4% of PO, 4 to 10% of LiO, 5 to 14% of NaO, 0 to 2% of KO, 0 to 11% of MgO, 0 to 5% of CaO, 0 to 20% of SrO, 0 to 15% of BaO, 0 to 10% of ZnO, 0 to 1% of TiO, and 0 to 2% of ZrO. A value of X is 30000 or more. The value of X is calculated based on the formula, X=SiO×329+AlO×786+BO×627+PO×(−941)+LiO×927+NaO×47.5+KO×(−371)+MgO×1230+CaO×1154+SrO×733+ZrO×51.8, by using the contents in mole percentage on an oxide basis of components.
