Abstract
<PICT:0655647/III/1> <PICT:0655647/III/2> <PICT:0655647/III/3> Silicon, titanium and zirconium oxides are produced by decomposing the chlorides with oxygen-containing or oxygeniferous gases at high temperature, the gases passing to the reaction chamber in concentric flow and one at least being in a state of spin. When both are spinning, the spin may be in the same or opposite direction. An inert gas, e.g. nitrogen, carbon dioxide or chlorine, or one which is inert only towards the chloride, e.g. hydrocarbons, carbon monoxide, hydrogen or mixtures thereof may be used to separate the reactant gas streams, or it may be fed in around the streams. Examples indicate a temperature of the various streams varying from 100 DEG C. to 900 DEG C. A variety of nozzles is shown. In Fig. 2, the outer feed duct 4 is sub-divided by helical partition walls 8, the edges of which may be spaced from the inner duct wall at 10. The helical walls need not extend to the outlet aperture. Fig. 5 shows a nozzle of truncated cone structure, the helical walls being not shown. By varying the angles a and b and the distance a, the mixing speed and distance b from the nozzles at which the gas currents contact, may be varied. Another form is shown wherein helical walls are disposed in the inner duct, and a further form with said walls in both ducts. There is also shown a core-member formed with helical flutes which may be pushed into the central delivery tube. Three further forms are illustrated, with three concentric ducts, helical walls being disposed respectively in the outer, outer and inner, and all three ducts. In the last, the intermediate helical walls are opposed in direction to the outer and inner helical walls. In Fig. 13, the outer duct is subdivided into straight channels 14 arranged in skew position with respect to the central axis of the nozzle. The channels may be arranged in a circle, ellipse or on any other figure around the central duct. Dimensions corresponding to a and b of Fig. 5 may be varied. Other arrangements include one or more circles of channels in combination with plain or helically-divided ducts. Channels 14 may be formed as bores in a thick plate. Specifications 535,214 and 567,093 are referred to. The Specification as open to inspection under Sect. 91 refers to the production of metal oxides generally, the decomposition of ferric chloride and aluminium chloride being referred to. This subject-matter does not appear in the Specification as accepted.
