TITANIUM OXIDE POWDER HAVING MODIFIED COLOR AND METHOD FOR PRODUCTION THEREOF

摘要

A titanium oxide powder having a modified color which is formed through the color modification of a white titanium dioxide powder from white to gray by collision and/or friction; and a method for producing the titanium oxide powder having a modified color which comprises placing a white titanium dioxide powder (11) in a metal vessel (13) and agitating the powder with a metal agitation member (15) while shaking the vessel. The above titanium oxide powder having a modified color is satisfactory in the deodorizing capability, antibacterial capability, anti-staining capability, and air- or water- clarifying capability, and exhibits satisfactory catalytic activity also in a dark place such as a toilet tank.
