GLASS, CRYSTALLIZED GLASS, PRODUCING METHOD OF CRYSTALLIZED GLASS AND PHOTOCATALYST MEMBER

摘要

PROBLEM TO BE SOLVED: To provide glass having transparency which can be preferably used as a material efficiently producing crystallized glass that can selectively crystalize a titanium oxide while sufficiently preventing the deposition of an Al4B2O9crystal and can exhibit a sufficiently high photocatalytic function, crystallized glass with deposited titanium oxide crystal which can be obtained using the glass, a producing method of the crystalized glass, and a photocatalyst member. SOLUTION: The crystallized glass contains 5-25 mol% titanium oxide, 3-15 mol% bismuth oxide, 45-75 mol% boron oxide, 5-25 mol% aluminium oxide, and 2-15 mol% alkaline earth metal oxide, and has deposited the titanium oxide crystal.
