  • Transparent ceramic structure and surface treatment method of the same
    Publication number: 20060093738
    Abstract: A transparent ceramic structure and a method of surface treatment thereof are disclosed. A glass powder is applied over an unpolished surface of an intrinsically transparent ceramic structure. The ceramic structure is then placed in high temperature which is higher than the melting temperature of the glass powder and lower than 1,700° C. for about 1 minute to about 5 minutes. The transparent ceramic structure is removed from the environment and cooled down so as to obtain the desired transparency and strength of the ceramic structure.
    Type: Application
