Abstract
Process and apparatus for the production of finely-divided metal oxides by the oxidation of the corresponding metal halide wherein a secondary gas is introduced into a heated primary gas through apertures in the reaction zone wall, the apertures formed with at least two different cross-sectional areas along their length, the small cross-sectional area being at the inlet end of the aperture for the secondary gas.
