DUAL STAGE ION EXCHANGE FOR CHEMICAL STRENGTHENING OF GLASS
A method of chemically strengthening a glass. The method includes ion exchange of the glass in a first bath, followed by immersion in the second bath. The first bath is diluted with an effluent ion. The second bath has a smaller concentration of the effluent ion than the first bath. The method provi...

Summary: | A method of chemically strengthening a glass. The method includes ion exchange of the glass in a first bath, followed by immersion in the second bath. The first bath is diluted with an effluent ion. The second bath has a smaller concentration of the effluent ion than the first bath. The method provides a compressive stress at the surface of the glass that is sufficient to arrest flaws introduced by contact forces at the surface of the glass while having sufficiently deep compressive depth-of-layer for high reliability. |
