摘要： The method, apparatus and product relate to the electrochemical reduction of a solid feedstock (20) to produce a product. A container (2) is filled with a fused salt (6), and one or more anodes (14) contact the fused salt. A cathode (18) is loaded with feedstock and engages with a transport apparatus (22, 36, 40) which locates and moves the cathode past the anodes(s), while the cathode and the feedstock contact the fused salt. As the cathode moves past the anodes(s), a voltage applied between the cathode and the anode(s) electrochemically reduces the solid feedstock to form the product.

摘要： A method for the production of an intermetallic compound (M1Z) involves treating a solid precursor material comprising three or more species, including first and second metal or metalloid species (M1, Z) and a non-metal species (X), by electro-deoxidation in contact with a melt comprising a fused salt (M2Y) under conditions whereby the non-metal species dissolves in the melt. The first and second metal or metalloid species form an intermetallic compound. The method is performed in a cell comprising a cathode of the precursor material (2), which is immersed in a melt (8) contained in a crucible (6) for electro-deoxidation.

摘要： A method of recycling useful metals is provided. The method enables useful metals including indium, zinc, yttrium, europium, lanthanum, terbium, gadolinium, antimony, lead, copper, tin, and silver to be recovered from wastes, such as wasted flat panel displays, and recycled economical with small energy consumption. The method of recycling useful metals includes: a step in which wastes comprising various flat panel displays, e.g., liquid-crystal display panels, are crushed/powdered; a step in which the resultant particles are dissolved in an aqueous hydrofluoric acid solution; and a step in which various metal oxides and various metal fluorides which remain undissolved are filtered off and the aqueous hydrofluoric acid solution containing various metal ions is electrolyzed to deposit and recover metals for transparent-electrode oxides, such as indium and zinc, and other useful metals.

摘要： A method of manufacturing titanium or titanium alloy semi-finished or ready-to-use products is disclosed. The method includes forming shaped bodies of titanium oxide particles and positioning the shaped bodies in an electrolytic cell which includes: an anode, a cathode, and a molten electrolyte. The shaped bodies are positioned to form at least a part of the cathode. The electrolyte includes cations of a metal that is capable of chemically reducing titanium oxide. The method further includes reducing the titanium oxide to titanium in a solid state in the electrolytic cell so that the shaped bodies become shaped bodies of titanium sponge. Finally, the method includes processing the shaped bodies of titanium sponge to reduce the volume or at least one of the dimensions of the bodies thereby to form the semi-finished or ready-to-use products.

摘要： A method of removing oxygen from a solid metal, metal compound or semi-metal M1O by electrolysis in a fused salt of M2Y or a mixture of salts, which comprises conducting electrolysis under conditions such that reaction of oxygen rather than M2 deposition occurs at an electrode surface and that oxygen dissolves in the electrolyte M2Y and wherein, M1O is in the form of (sintered) granules or is in the form of a powder which is continuously fed into the fused salt. Also disclosed is a method of producing a metal foam comprising the steps of fabricating a foam-like metal oxide preform, removing oxygen from said foam structured metal oxide preform by electrolysis in a fused salt of M2Y or a mixture of salts, which comprises conducting electrolysis under conditions such that reaction of oxygen rather than M2 deposition occurs at an electrode surface. The method is advantageously applied for the production of titanium from Ti-dioxide.

摘要： The disclosed process is characterized in that the electrolysis is conducted in such a way that the voltage of deposition of said transition metal is lower by 0,1 - 0,4 volt than that of the alkaline or alkaline earth metal which is the easiest to reduce. The process may be applied to the production of powders whose sizes range from a few fractions of microns to 200 microns approximately of metals pertaining to the columns IVb, Vb, VIb of the periodic classification such as for example titanium, zirconium, hafnium.
