  • Titanium dioxide process
    Publication number: 20080075654
    Abstract: A process for producing titanium dioxide is disclosed. The process is cooled with liquid titanium tetrachloride in a gas-phase reaction. This enables good temperature control of the exothermic reactions even at high production rates.
    Type: Application

  • Methods of producing substantially anatase-free titanium dioxide with silicon halide addition
    Patent number: 6562314
    Abstract: 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.
    Type: Grant
