| abstract | 9676. British Aluminium Co., [Cowles, A. H.]. May 9. Electric furnaces. -An arc furnace, for decomposing sodium aluminate, preparing alloys &c., is lined with carbon f sufficiently porous for vapour such as sodium to pass through it and a perforated wall into a casing g, provided with a water jacket to condense the sodium to liquid form, which is drawn off from time to time through the cock k. Aluminium is run. off through a tap hole j. The ore or compound, such as a mixture of sodium aluminate and carbon, is fed in from a hopper fitted with a pair of valves v. The carbon lining f forms one electrode ; the other electrode c slides in a tube s, into which hydrocarbon gas or the like is forced through a pipe t to exclude sodium vapour. The gas produced in the furnace is discharged through a pipe i. By adding non- volatile metals such as tin or copper to the charge, alloys may be obtained in the furnace ; or by adding a volatile metal such as zinc, the alloy may be collected in the easing g. Aluminium carbide is obtained by continuing the current with excess of carbon, while calcium carbide may be obtained by treating a mixture of sodium salt and a calcium compound. |
