WIPO Patent Application WO/2019/064674

Kind Code:

A1

Abstract:

The purpose of the present invention is to produce a titanium material, on the surface of which a crystalline titanium oxide film is formed. This titanium material, on the surface of which a crystalline titanium oxide film is formed, is useful as a photocatalyst material that exhibits a high function, a material for photoelectric conversion elements, a wear-resistant member, a member for preventing deterioration of edible oils, and the like. A method for producing a titanium material, on the surface of which a crystalline titanium oxide film is formed, according to the present invention is characterized by comprising: (1) a step for forming a surface roughened material by subjecting the surface of a titanium material to a surface roughening treatment; (2) a step for forming a titanium compound on the surface of the surface roughened material; (3) a step for forming an amorphous titanium oxide film by subjecting the material, on the surface of which a titanium compound is formed, to anodic oxidation; and (4) a step for forming a crystalline titanium oxide film by heating the material, on the surface of which an amorphous titanium oxide film is formed, at a temperature of 300°C or higher in the atmosphere.
