Title of Invention	PROCESS FOR THE PRODUCTION OF COATED TITANIUM DIOXIDE PIGMENTS
Abstract	A process for the preparation of pigment-grade titanium dioxide is provided that produces substantially anatase-free titanium dioxide with a uniform coating of a metal oxide without producing separate particles of the metal oxide that are not incorporated into the coating. The process comprises mixing a titanium dioxide precursor with a silicon compound to form an admixture and introducing the admixture and oxygen into a reaction zone to produce substantially anatase-free titanium dioxide. The titanium dioxide produced is contacted with a metal oxide precursor homogeneously mixed with a solvent component downstream of the reaction zone to form a uniform coating of the metal oxide on the titanium dioxide particles.
