| abstract | 1,145,290. Producing metal oxides. AMERICAN CYANAMID CO. 25 April, 1966 [10 Nov., 1966], No. 36925/66. Heading C1A. Finely divided metal (including silicon) oxides are prepared continuously by reacting a freeoxygen containing stream and at least one stream of at least one vaporous metal salt in a reaction zone wherein at least one of the reactant streams is mixed with a stream of gaseous fluid at a temperature in the range 3000-12,000 C., the reactant streams are mixed in a dome-shaped mixing zone having no geometrical discontinuities in its connection to the reaction zone, the streams flowing into the mixing zone at an angle with respect to each other of between 25 and 160 degrees and the reactants are maintained in the reaction zone for a period of 0À001-1 second. The vaporous metal salt is preferably a silicon or titanium tetrachloride, the titanium tetrachloride optionally containing 0À16-6À3% of aluminium chloride based on the weight of product titanium dioxide. Zr is also mentioned. The process may be carried out in apparatus shown in the Figures embodying a preferred, spherical mixing zone. The gaseous fluid is supplied through ports 13, 20 to the plasma generators 10 where the fluid is converted to a plasma between the electrodes 11 and 12 and 18 and 19. The reagent streams are injected tangentially into the plasma streams through parts 15, 22, the streams flow through a constriction 17, 24 and pass into the hemispherical mixing zone 25 at an angle # with respect to each other. The mixing zone 25 is identical in radius to the reaction vessel 26 and there is no discontinuity between the two so that the reaction mixture flows into the reaction chamber and the oxide product does not build up on the walls. The oxide formed is cooled in heat exchanger 27 and released through pipe 28 to collecting means. |
