  • CHEMICALLY STRENGTHENED GLASS AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20230271879
    Abstract: The present invention relates to a chemically strengthened glass, satisfying: a ratio ICS (?400)/ICS being more than 0.13 in a stress profile, the ICS representing an integrated value of compressive stress in a region from a surface of the glass to a depth where the compressive stress becomes 0 in the stress profile, and the ICS (?400) representing an integrated value of compressive stress in a region from a depth of 400 ?m from the surface of the glass to the depth where the compressive stress becomes 0 in the stress profile.
