PROBLEM TO BE SOLVED: To provide a chemically strengthened crystallized glass article having high mechanical strength and excellent designability, and a method for producing the same.SOLUTION: A chemically strengthened crystallized glass article is obtained by depositing crystals of one or more selected from rutile (TiO), MgO-2TiOand zirconia (ZrO) and has a compressive stress layer formed on a surface thereof. Specifically, the article is made of crystallized glass comprising, in mass%, 40-60% of SiO, 0.5-10% of TiO+ZrO, 10-25% of AlO, 2-15% of BO, 2-20% of NaO+KO+LiO, and 0-20% of ZnO+MgO+CaO+BaO. |
