Abstract: The present invention relates to a new electrolysis cell for the fusion electrolytic extraction of aluminum wherein the anode blocks are connected to one another using a compressed granulate packing. The invention also relates to a novel electrolytic cell wherein the cathode blocks are separated one from another and have sloped or curved upper surfaces allowing newly formed aluminum to drain into an underlying receptacle area.

Abstract: A method for the manufacture of refractory, bricks that are resistant to molten iron and slag. The bricks are made of refractory oxides and/or the corresponding hydroxides and carbon by mixing fine-particle refractory oxides and/or the corresponding hydroxides with pitch to form a homogeneous green mixture, heating the green mixture in the presence of carbon to form a solid thermally stable sintered product of oxide and carbon, reducing the sintered product into smaller size particles, binding the reduced sintered particles with a mixture of refractory oxide and/or corresponding hydroxide and pitch, compacting the thus obtained substance into a green molded article, and firing the green molded article in a reducing atmosphere to form refractory bricks.

Abstract: The invention concerns a process for producing aluminum by molten salt electrolysis, whereby a melt consisting of alkali halides and/or alkali earth halides is used as electrolyte and a mixture containing aluminum oxide and carbon is used as the anode.

Abstract: A method and apparatus for the continuous production of metals and/or carbides by thermal reduction is described. In the process, a mixture of metal oxide and carbon is agglomerated, each piece of agglomerate encased in carbon and/or graphite, the carbon casing serves as a housing of the agglomerate during the reducing reaction and as an electrical resistance element for heating of the agglomerate, the encased agglomerates are coked and reduced to metal carbide in a tightly-packed form. Extraction of the metal from the carbide is effected with a halide of the same metal.
