Abstract
Finely divided oxides of titanium, silicon, zirconium and aluminium are produced by discharging a mixture of the volatile chloride and oxygen-containing gas (reaction gas) at a temperature not exceeding 500 DEG C. into a reaction chamber and igniting the mixture to form a flame with the aid of an auxiliary chemical reaction delivering at least the amount of heat necessary for the ignition of the reaction mixture. The gas mixture composition, its temperature and exit velocity are preferably so chosen that the flame is kept at leat 1 mm. and up to 1 m, from the outlet opening for the gases. The oxygen-containing gas may be mixed with the chloride by feeding it to the still or sublimation chamber for the chloride, or by using it to atomize the superheated chloride. The auxiliary chemical reaction suitably consists in the combustion of hydrogen, carbon monoxide, oil vapours, &c. and the oxygen required, or a part thereof may be fed in admixture with the reaction gas. Concentric feed of the gases may be employed when carbon monoxide is used, this may surround the reaction gas, the separately fed oxygen-containing gas constituting the outer layer. The latter gas should however constitute the intermediate layer when hydrogen is employed. The direction of at least one of the outer gas streams suitably intersects that of the reaction gas stream, the combustible gas and oxygen-containing gas fed separately may be given a spin around the reaction gas, which also may spin in the same or opposite direction. A supply of heat additional to that provided by the exothermic chemical reaction may be furnished; thus, the walls of the reaction chamber may be heated. A variety of burner nozzles is shown consisting of three concentric tubes in which, (a) one or more is formed with helical partition walls to promote spinning of the gases, (b) the outer, or the outer and intermediate, tube terminate in a ring of small nozzles directed skew to the axis of the central tube, and (c) the outer, or the outer and intermediate ducts converge. The Specification as open to inspection under Sect. 91 is not restricted to the treatment of the four chlorides referred to above. It also comprises ignition of the reaction gas by other means. Thus, the use of a resistance heater protected by a ceramic tube, and of an electrode heater is illustrated. This subject-matter does not appear in the Specification as accepted.
