Title: METHOD FOR PRODUCING CHEMICALLY TOUGHENED GLASS
Abstract:
The present invention provides a method for producing a chemically toughened glass, which improves the texture to the touch of the glass. The present invention relates to a method for producing a chemically toughened glass, which comprises: a step for preparing a glass containing alkali ions; a step for preparing an inorganic salt which contains other alkali ions that have a larger ionic radius than the alkali ions contained in the glass, and which has a pH of 8 to 14 (inclusive) when formed into a 10 wt% aqueous solution; and a step for performing ion exchange between the alkali ions contained in the glass and the other alkali ions contained in the inorganic salt in an atmosphere having a dew point of 39°C or higher.
