Abstract

Lower halides of titanium, vanadium, niobium, molybdenum, tantalum, and tungsten are prepared by reducing the normal halides with hydrogen in the presence of a molten alkali metal or alkaline earth metal halide at at least 450 DEG C. The sub-halides so produced are then reduced to the metal (see Group II). The reduction may be effected by passing the normal halides in admixture with hydrogen through a column containing molten alkali metal halides or the latter may be trickled down a tower countercurrent to the halide/hydrogen mixture. Examples refer to the production of titanium and niobium lower chlorides, using chlorides of sodium, potassium, lithium and magnesium, and mixtures thereof. Specifications 479,014 and 632,564 are referred to.ALSO:Titanium, vanadium, niobium, molybdenum, tantalum and tungsten are prepared by reducing the normal halides thereof with hydrogen in the presence of molten alkali metal or alkaline earth metal halides at at least 450 DEG C. and thereafter reducing to metal the sub-halide formed, by reduction with an alkali or alkaline earth metal, zinc or aluminium or alloys thereof. Sub-halide production is effected at temperatures above 450 DEG C. and generally from 750 DEG to 850 DEG C. whilst the reduction to metal may be at 700 to 1100 DEG C. According to examples (7) a solution of titanium sub-chloride in molten sodium chloride, (formed by passage of a titanium tetrachloride/hydrogen mixture counter-current to a downwardly flowing molten sodium chloride stream in a packed tower) was passed from the tower to a reaction chamber where at 950 DEG C. it was treated with a stream of sodium to form titanium sponge metal. (10) A solution of lower titanium chlorides in molten magnesium chloride was prepared by reacting titanium tetrachloride and hydrogen. The resultant solution was heated to 800 DEG C. and 1/4 " cubes of magnesium were added with stirring. After cooling the magnesium chloride was removed by water leaching to leave titanium sponge. (11) Niobium pentachloride was reduced with hydrogen in the presence of a sodium chloride-potassium chloride eutectic and the resulting salt composition was mixed with a zinc magnesium alloy containing 59% of zinc, and heated in an alumina crucible in an argon atmosphere at 75 DEG C.; after cooling the product was leached with 6 N hydrochloric acid and vacuum distilled at 1300 DEG C. to produce a 99.96% purity niobium. The molten salt composition before reduction may be filtered through a fritted silica disc. Further examples relate to niobium production from an alkali metal halide/lower niobium halide molten mixture employing magnesium, sodium, and aluminium. Specifications 479,014 and 632,564 are referred to.
