DECORATIVE POROUS INORGANIC LAYER COMPATIBLE WITH ION EXCHANGE PROCESSES

摘要

Embodiments of methods for forming strengthened glass articles comprise providing an exchangeable glass substrate having a coefficient of thermal expansion (CTE) between about 60×10−7°/C. to about 110×10−7°/C., depositing at least one decorative porous inorganic layer onto at least a portion of the surface of the glass substrate, wherein the decorative porous inorganic layer comprises a glass transition temperature (Tg)≧450° C., a glass softening temperature (Ts)≧650° C., wherein the difference in CTE values between the glass substrate and the decorative porous inorganic layer is within 10×10−7°/C.; and curing the glass substrate and the deposited decorative porous inorganic layer at a temperature greater than the Ts of the decorative porous inorganic layer; and chemically strengthening the cured glass substrate and the decorative porous inorganic layer thereon via ion exchange at a temperature below the Tg of the decorative porous inorganic layer.

1. A method for forming a strengthened glass article, the method comprising:
providing an ion exchangeable glass substrate having a coefficient of thermal expansion (CTE) ranging between about 60×10−7/° C. to about 110×10−7/° C.; depositing at least one decorative porous inorganic layer onto at least a portion of the surface of the glass substrate, wherein the decorative porous inorganic layer comprises a glass transition temperature (Tg)≧450° C., a glass softening temperature (Ts)≦650° C., wherein the difference in CTE values between the glass substrate and the decorative porous inorganic layer is within 10×10−7° C.; curing the glass substrate and the deposited decorative porous inorganic layer at a temperature greater than the glass softening temperature (Ts) of the decorative porous inorganic layer; and chemically strengthening the cured glass substrate and the decorative porous inorganic layer thereon via ion exchange at a temperature above the glass transition temperature (Tg) of the decorative porous inorganic layer.
