る。(Function/Effect) By anodizing titanium material, grayish titanium dioxide (TiO2) is formed, and by heating this titanium dioxide to 300°C or higher under reduced pressure of 10''-3 torr or less. , the titanium dioxide is reduced, and among the lower titanium oxides represented by the general formula T1n02n-1 (where n = 1 to 10), blackish ions become a black film and are exposed on the surface of the titanium material. This makes it a decorative item or building material with good appearance and excellent weather resistance.In addition, the lower titanium oxide has an excellent oxygen adsorption function, so it can also be used as a reducing agent. When reducing the titanium material that has been subjected to anodic oxidation treatment, if the pressure condition is 10-3 torr or more, or if the heating condition is 300°C or less, the reduction of the titanium dioxide formed by anodizing treatment is required. The process is carried out under the above-mentioned conditions because the initial objective cannot be achieved because the formation of titanium oxide and dititanium pentoxide is difficult to achieve.
