化学强化玻璃
摘要：
一种化学强化玻璃，其在表层具有通过离子交换法形成的压应力层，其中，表面粗糙度(Ra)为0.20nm以上，从玻璃的最外表面起的深度X的区域中的氢浓度Y在X＝0.1～0.4(μm)的情况下满足下述关系式(I)，通过环上球试验测定的面强度F(N)对于玻璃板的板厚t(mm)为F≥1500×t2，并且在表面上没有磨痕，Y＝aX+b(I)，式(I)中的各符号的含义如下所示：Y：氢浓度(按H2O换算，mol/L)，X：从玻璃最外表面起的深度(μm)，a：‑0.270～‑0.005，b：0.020～0.220。
摘要（英）：

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 K2CO3, Na2CO3, KHCO3, NaHCO3, K3PO4, Na3PO4, K2SO4, Na2SO4, 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.
