  • Method for reinforcing transparent ceramics, and ceramic
    Patent number: 10752555
    Abstract: A method for producing a transparent polycrystalline ceramic includes forming at least one planar transparent region near a surface within the ceramic, wherein the at least one planar transparent region has a lower thermal expansion coefficient than other regions of the ceramic. The method further includes generating compressive stresses in the at least one planar transparent region near the surface after a thermal treatment and cooling.
