Tempered method of alkaline aluminosilicate glass and the same glass article |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for generating various stress profiles for chemically strengthened glass. An alkali aluminosilicate glass is brought into contact with an ion exchange medium such as a molten salt bath containing alkali metal cations larger than the alkali metal cations in the glass. Ion exchange is carried out at a temperature above about 420 ° C. and at least about 30 ° C. below the slow cooling point of the glass. The compressive stress at the first depth is at least 70% of the compressive stress on the surface and lower than the compressive stress on the surface, and the first depth is 30% to 70% of the layer depth. , The compressive stress at the first depth is a maximum value.
