摘要： A method for producing a metal powder includes maintaining molten reducing metal in a sealed reaction vessel that is free of added oxygen and water, establishing a vortex in the molten reducing metal, introducing a metal halide into the vortex so that the molten reducing metal is in a stoichiometric excess to the metal halide, thereby producing metal particles and salt, removing unreacted reducing metal, removing the salt, and recovering the metal powder. The molten reducing metal can be a Group I metal, a Group II metal, or aluminum.

摘要： This invention relates to a method for controlling exothermic reactions between metal chlorides of Zn, V, Cr, Co, Sn, Ag, Ta, Ni, Fe, Nb Cu, Pt, W, Pd, and Mo, and Al and the use of the method for preparation of metallic alloys and compounds based on base metals Zn, V, Cr, Co, Sn, Ag, Ta, Ni, Fe, Nb Cu, Pt, W, Pd, and Mo. The method provides for a mixture of precursor chemicals including at least one solid base metal chloride to be mixed and reacted exothermically with a control powder based on Zn, V, Cr, Co, Sn, Ag, Ta, Ni, Fe, Nb Cu, Pt, W, Pd, and Mo and then reacting the resulting intermediates with an Al scavenger. Reduction is carried out in a controlled manner to regulate reaction rates and prevent excessive rise in the temperature of the reactants and the reaction products.

摘要： Carbothermic reduction of magnesium oxide at approximately 2200 degrees Kelvin yields a high temperature mixture of magnesium vapors and carbon monoxide gas. Previous processes have sought to cool or alter the mixture to cause the yield of pure magnesium, which is then used in subsequent processes for its reducing properties. The present invention takes advantage of the stability and inertness of carbon monoxide at elevated temperatures enabling the magnesium vapor/carbon monoxide gas mixture from the carbothermic process to be used directly for the production of other metals at high temperatures. Chromium oxide, manganese oxide, zinc oxide and sulfide, and several other metal compounds can be reduced by the magnesium vapor/carbon monoxide gas mixture at temperatures high enough to prevent the gas mixture from back-reacting to magnesium oxide and carbon.

摘要： Disclosed herein are reactors and methods for forming alloys based on titanium-aluminium or alloys based on titanium-aluminium inter-metallic compounds. The reactor comprises a first section having an inlet through which precursor material comprising titanium subchlorides and aluminium can be introduced. The first section is heatable to a first temperature at which reactions between the titanium subchlorides and aluminium can occur, and further comprises a gas outlet via which any gaseous by-product formed can be removed. The reactor also comprises a second section which can be heated to a second temperature at which reactions of material transferred from the first section can occur to form the titanium-aluminium based alloy, a gas driver adapted in use to cause any gaseous by-product formed in the reactions in the second section to move in a direction towards the first section, and an intermediate section between the first and second sections. The intermediate section can be heated to an intermediate temperature at which at least a portion of material transferred from the first section can accrete and form a cake on a surface of the intermediate section and at which gaseous by-product formed in the reactions in the second section can be received and condensed. The reactor also comprises a removing apparatus for removing caked material from the surface of the intermediate section and transferring it to the second section.
