摘要：
The present invention provides methods of producing substantially anatase-free titanium dioxide by mixing titanium tetrachloride with a silicon compound to form an admixture, and introducing the admixture and oxygen into a reaction zone to produce the substantially anatase-free titanium dioxide. The reaction zone has a pressure of greater than 55 psig.
