Tronox LLC has been granted a patent for a process for manufacturing titanium dioxide comprised of continuously reacting a titanium halide and an oxygen-containing gas in the vapor phase to produce titanium dioxide particles and gaseous reaction products. The reaction is carried out by combining a reactant stream of the titanium halide and a reactant stream of the oxygen-containing gas in a reaction zone of a vapor phase oxidation reactor at a temperature of at least 700° C; introducing a particle size control agent into the reaction zone to control the particle size of the titanium dioxide, the particle size control agent including an ionizing agent and fumed silica; and separating the titanium dioxide particles from the gaseous reaction products.
