Abstract
242,958. Haglund, T. R. Nov. 15, 1924, [Convention date]. Aluminium and alloys, obtaining.-Aluminium and its alloys are obtained by electrolysis of a molten electrolyte compounded of crystalline aluminium oxide of high specific gravity, such as that formed by crystallization from a melt, e.g. corundum, and amorphous aluminium oxide of lower specific gravity, e.g. such as is obtained by calcination of the hydrate or salts of aluminium. The crystalline oxide must be of sufficient purity to be used for the production of aluminium of common commercial quality when subjected to electrolysis in the presence of a molten electrolyte. The use of the mixture is stated to minimize the formation of a solid crust on the molten bath and prevents blowing away of the amorphous alumina. A proportion of 10 to 40 per cent of amorphous oxide to the whole is suitable. The oxides may be mixed before charging or added separately. In the latter case, the amorphous oxide should be added immediately after the crystalline oxide. Specification 232,189 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to Specification 232,549, [Class 1 (iii), Oxides &c., Metallic]. This reference does not appear in the Specification as accepted.
