Abstract
1,199,811. Discharge in gases. BRITISH TITAN PRODUCTS CO. Ltd. 4 Feb., 1969 [9 March, 1968], No. 11634/68. Heading H5H. [Also in Division C1] An apparatus is described for the production of nitrides by establishing a high energy electrical discharge in a stream of a vaporized halide (Al, Si, B, Zr or Ti) or in a mixture of the halide and an inert gas, in order to heat the halide and then reacting the heated halide with ammonia. Preferably the heating of the halide is effected in a volume of plasma which is maintained in a gas-containing tube having heat-resistant walls (e.g. of silica) by the passage of a R/F oscillatory electric current around the tube in order to introduce in the halide an area of electrical discharge of sufficient energy to heat the gas stream. The gasconfining tube may be surrounded over at least a portion of its surface with a coil of an electrically conducting material, e.g. a coil of copper tube. In Fig. 1 (not shown), the gas confining tube (1) has a copper coil (2) surrounding a portion of its surface connected to a source of R/F oscillatory electric current. The tube is provided with a gas distribution head (3) and the whole is mounted on a silica reactor (4) having an exit tube (5) passing through a water-cooled condenser (6) to a filter (7). The tube (8) allows agglomeration of the product particles before filtering. The bag filter is connected to a scrubber (12) filled with NaOH solution to remove acidic by-products from the gas stream prior to discharge through vent (15). Halide contained in vessel (76) passes through vaporizer (20) to distribution head (3) which is supplied with a further inlet (25) through which an inert gas may be fed to initiate a plasma. The distribution head is so designed to introduce the stream of halide vapour or mixture thereof with an inert gas into the high energy electric discharge in such a manner that the stream follows a helical path. A gas distribution head for use with a titanium halide (Fig. 2, not shown), is equipped with a probe through which the halide is introduced and which terminates part of the way through the electric discharge so that the halide is mixed with already heated inert gas. Ammonia is introduced through vent (24) into the heated halide or halide/inert gas mixture.
