Abstract

Boron, silicon and those metals of which the <PICT:0928853/III/1> halides are capable of forming addition compounds with ammonia, particularly the light metals, the transition metals, germanium and tin, are extracted from their halides in a two stage process. In the first stage an intermediate addition product is formed of the halide with ammonia or at least two of the gases nitrogen, hydrogen and ammonia, the product persisting at least for a short time, and in the second stage the metal is obtained from this intermediate product. In a particular process described, liquid halide 11 from nozzle 12 (Fig. 1) reacts in vessel 13 with gaseous reagent from nozzles 15, forming a solid intermediate product which is transferred by screw conveyer 21 to conveyer 24 which carries it through chamber 25. In this zone the intermediate product is acted upon by streams of hydrogen and/or nitrogen which have been ionized by passage through electrodes 35, to yield a free metal product 26. In a modification shown in Fig. 2, the two stages of the reaction take place within the same chamber. By insulating nozzle 12 from the container and applying a suitable voltage, the first stage of the process may be carried out under partial ionization. As an alternative second stage of the process, the intermediate product may be calcined in ammonia to yield a substance which may be dissolved in a fused salt electrolyte and the metal recovered by electrolysis, or which may be treated with nitric acid before such electrolysis. Specifications 804,916 and 901,022 are referred to.
