Abstract
Official abstract text for this publication.
A method for producing a chemically strengthened glass, including a step of bringing a glass containing sodium into contact with an inorganic salt containing potassium nitrate, thereby performing ion exchange of a Na ion in the glass with a K ion in the inorganic salt, in which the inorganic salt contains at least one salt selected from the group consisting of K 2 CO 3 , Na 2 CO 3 , KHCO 3 , NaHCO 3 , K 3 PO 4 , Na 3 PO 4 , K 2 SO 4 , Na 2 SO 4 , KOH and NaOH, and the method includes: a step of washing the glass after the ion exchange; a step of subjecting the glass to an acid treatment after the washing; and a step of subjecting the glass to an alkali treatment after the acid treatment.
