摘要： The present invention pertains to a method for electrolytic reduction of feedstock elements, made from feedstock, in a melt. In addition, the present invention relates to an apparatus for electrolytic reduction of feedstock elements, made from feedstock, and can be used for the reduction of oxides of metals belonging to Groups 3-14 of the Periodic Table. The method is implemented using the apparatus that, according to the invention, comprises an electrolyzer bath; an electrolytic cell; an electrolyzer bath insert plate; a cover with evolved gas outlets. Moreover, the electrolytic cell contains at least one cathode chamber and two anode plates, which are vertically arranged relative to each other, at least one current source, independently connected to the cathode chamber and one or two anode plates, and a device for horizontal reciprocating movement of the said electrolytic cell, which is found outside of the electrolyzer cover.

摘要： A method and an apparatus for manufacturing a metallic article involve providing a non-metallic feedstock, for example in the form of an oxide of a desired metal or a mixture of oxides of the components of a desired metal alloy. A manufacturing apparatus has a reduction apparatus for electrochemically reducing the feedstock to a metallic product and a processor for converting the metallic product to a metallic powder. The powder is fed into an additive-manufacturing apparatus for fabricating the metallic article from the metallic powder. At least the reduction apparatus and the processor, and preferably also the additive-manufacturing apparatus, are collocated, or located in the same container, or in the same building, or on the same site.

摘要： A process of producing metal that includes adding a quantity of a alkoxide (M(OR)x) or another metal salt to a cathode compartment of an electrolytic cell and electrolyzing the cell. This electrolyzing causes a quantity of alkali metal ions to migrate into the cathode compartment and react with the metal alkoxide, thereby producing metal and an alkali metal alkoxide. In some embodiments, the alkali metal is sodium such that the sodium ions will pass through a sodium ion selective membrane, such as a NaSICON membrane, into the cathode compartment.
