Latest Patents
Kazumasa Ejiri holds a patent for a method of producing titanium oxide powder that contains rutile-type crystals. The patent describes a process where hydrochloric acid is added to an aqueous dispersion of an alkali metal titanate, along with sulfurous acid, disulfurous acid, sulfuric acid, or a salt thereof. This method results in a titanium oxide powder doped with bivalent sulfur atoms. The unique feature of this powder is that it has a peak intensity ratio of anatase-type to rutile-type crystals of 0.1 or less, as measured by X-ray diffractometry. This innovation negates the bluish color derived from Rayleigh scattering, providing excellent transparency and color tone, particularly in cosmetic applications.
