POWDER OF TITANIUM DIOXIDE CONTAINING IRON OXIDE, PREPARATION THEREOF AND SAID POWDER CONTAINING COSMETICS, COATING MATERIAL, CATALYST, PHOTOCATALYST AND ULTRAVIOLET RAY ABSORBENT

摘要

Titanium dioxide powder containing iron oxide is prepared by a pyrogenic, in particular a flame-hydrolytic, route from FeCl3 and TiCl4. A further possibility is the coating of pyrogenic titanium dioxide, in particular prepared by flame hydrolysis, with iron oxide in aqueous dispersion. The titanium dioxide containing iron oxide is used as a UV absorber in sun protection compositions.
