| 20110308965 | METHOD FOR PRODUCING METAL POWDERS - A method of producing metallic powder for use in the manufacture of a capacitor comprises the step of reducing a non-metallic compound to metal in contact with a molten salt. The salt comprises, for at least a portion of the process, a dopant element that acts as a sinter retardant in the metal. In preferred examples, the metallic powder is Ta or Nb powder produced by the reduction of a Ta or Nb oxide and the dopant is boron, nitrogen, or phosphorous. | 12-22-2011 |
| 20110158843 | Electrolytic reduction of metal oxides such as titanium dioxide and process applications - 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 perform, 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. | 06-30-2011 |
