  • Crystallized glass substrate
    Patent number: 11926561
    Abstract: To provide a crystallized glass substrate including a surface with a compressive stress layer, in which a compressive stress CS (MPa) on an outermost surface of the compressive stress layer is 400 to 1400 MPa, and DOL50%/DOLzero is 0.30 or more, where DOL50% (?m) is a depth at which the value of the compressive stress is 50% of the CS and DOLzero (?m) is a depth at which the value of the compressive stress is 0 MPa.
    Type: Grant
    Filed: August 9, 2018
    Date of Patent: March 12, 2024

  • Crystallized glass substrate
    Patent number: 11926559
    Abstract: To provide a crystallized glass substrate including a surface with a compressive stress layer, in which a stress depth DOLzero of the compressive stress layer, at which the compressive stress is 0 MPa, is 45 to 200 ?m, a compressive stress CS on an outermost surface of the compressive stress layer is 400 to 1400 MPa, and CS×DOLzero, which is a product of the compressive stress CS on the outermost surface and the stress depth DOLzero (?m), is 4.8×104 or more.
