The production of pigmentary metal oxides, e.g., titanium dioxide, by vapor phase oxidation of the corresponding metal halide, e.g., titanium tetrachloride, in a reaction zone is described. The results of ineffective mixing of reactant gases introduced into the reaction zone through an annulus id discussed and a method comprising deflecting the gas as it enters the annulus proposed for effecting more uniform mixing in the reaction zone. |
