Abstract:
A glass for chemical strengthening contains, in mole percentage on an oxide basis, 58 to 80% of SiO 2 , 13 to 18% of Al 2 O 3 , 0 to 5% of B 2 O 3 , 0.5 to 4% of P 2 O 5 , 4 to 10% of Li 2 O, 5 to 14% of Na 2 O, 0 to 2% of K 2 O, 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 2 , and 0 to 2% of ZrO 2 . A value of X is 30000 or more. The value of X is calculated based on the formula, X=SiO 2 ×329+Al 2 O 3 ×786+B 2 O 3 ×627+P 2 O 5 ×(−941)+Li 2 O×927+Na 2 O×47.5+K 2 O×(−371)+MgO×1230+CaO×1154+SrO×733+ZrO 2 ×51.8, by using the contents in mole percentage on an oxide basis of components.

Claim (Index 6):
The glass for chemical strengthening according to  claim 1 , wherein the content of CaO in mole percentage on an oxide basis is 1% or less.
