Document Type and Number:
WIPO Patent Application WO/2017/209139
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide glass for chemical strengthening that is capable of achieving a higher compressive stress when chemically strengthened under predetermined chemical strengthening conditions. The present invention relates to the glass for chemical strengthening that includes, in mol% on an oxide basis, 60 to 67% of SiO2, 9 to 13.5% of Al2O3, 13.5 to 18.5% of Na2O, 0.1 to 3% of K2O, 6 to 10.5% of MgO, and over 0 to 5% or less of TiO2, wherein [(Na2O+K2O×5)/(Al2O3+ZrO2+TiO2×10)] is 2.55 or less, and Al2O3/ K2O is over 10.
