Abstract

Addition compounds of ammonia or hydrazine with halides, nitrates, nitrites, chlorates or perchlorates of Al, Mg, Be, Ca, Ti, Zr, Hf, Th, V, Nb, Ta, Mo, V, Ce, or the products obtained therefrom after heat treatment at preferably above 400 DEG C. in an inert oxygen-free atmosphere are suitable as electrolyte additives in the fusion electrolysis of metals (see Division C7). The preferred products contain the minimum number of ammonia or hydrazine molecules per molecule of metal compound. The invention is described in respect of the addition compounds of ammonia and aluminium chloride and titanium chloride formed in a vapour phase reaction with the aid of our apparatus (not shown) permitting operations to be performed in an inert atmosphere. Specification 965,766 is referred to.ALSO:In the production of metals by fusion electrolysis, e.g. Al and Ti, additives are added to a melt before or during or both before and during fusion electrolysis, said additives consisting of addition compounds of ammonia or hydrazine and halides, nitrates, nitrites or perchlorates of Al, Mg. Be, Ca, Ti, Zr, Hf, Th, V, Nb, Ta, Mo, U, and Ce, or the additives produced from these compounds by heat treatment of the latter in a protective atmosphere free from oxygen. The additive may be formed from the same or a different metal as the metal to be obtained and may comprise more than one metal which may or need not be identical with the metal to be obtained; in the latter cases alloys may be obtained. Particularly useful are stated to be the additive of ammonia and aluminium chloride in the fusion electrolysis of aluminium using alkali aluminium halide and up to 10% aluminium oxide, and the additive of ammonia and titanium halide, especially chloride, in the fusion electrolysis of an alkali metal titanium double fluoride. The amount of additive employed is preferably low, i.e. 0.2-5%. The examples relating specifically to aluminium and to titanium give data relating to economy in electricity consumption and lowering of operating temperatures. Specification 965,766 is referred to.
