TITANIUM DIOXIDE-MIXED OXIDE, PRODUCTION THEREOF AND METHOD FOR PRODUCTION OF CATALYST, CATALYST CARRIER, PHOTOCATALYST, CERAMIC, AUTOLACQUER AND COSMETICS

摘要

Titanium dioxide mixed oxide prepared by flame hydrolysis having a BET surface area of from 10 to 150 m<2>/g and containing from 1 to 20% by weight of aluminium oxide or from 1 to 20% by weight of silicon dioxide. It is prepared by vaporising aluminium chloride or silicon tetrachloride, transferring this together with an inert gas into the mixing chamber of a burner, mixing with hydrogen, air and gaseous titanium tetrachloride, burning the 4-component mixture in a reaction chamber and separating the titanium dioxide mixed oxide from the gaseous reaction products.
