Abstract
An ion-exchanged glass article manufacturing method includes an ion-exchange step of bringing a glass article with a composition containing Li into contact with a molten salt dissolved solution containing an alkali metal element having an ionic radius larger than an ionic radius of the Li contained in the glass article, thereby ion-exchanging the Li in the glass article with the alkali metal element in the molten salt dissolved solution. At least one kind of additive selected from the group consisting of NaF, KF, KAlF, NaCO, NaHCO, KCO, KHCO, NaSO, KSO, KAl(SO), NaPO, and KPOis added to the molten salt dissolved solution so that the ion-exchange step is carried out while the additive is in a solid state.
