    摘要： The invention relates to a process for the production of metal alloy powders, in particular the invention relates to a process for producing titanium metal alloys from titanium dioxide and aluminium. Optionally the process can also include the use of one or more other oxides (metal or non-metal). The result is at least a Ti—Al alloy powder. If another metal oxide is used the result is a Ti-ternary alloy powder. If SiO2 is used the result is a Ti—Al—Si alloy.

    摘要： A method for reducing titanium and other metal oxides to metal is disclosed. The method comprises providing a titanium or other metal oxide exposing the metal oxide to a non-thermal plasma, and reducing at least a portion of the titanium oxide to provide titanium metal. The non-thermal plasma may be formed using a first inert gas species, and a second reactive gas species.

    摘要： A method of producing an elemental material or an alloy thereof from a halide or mixtures of halides is provided. The halide or mixtures thereof are contacted with a reducing gas in the presence of reductant material, preferably in sufficient quantity to convert the halide to the elemental material or alloy and to maintain the temperature of the reactants at a temperature lower than the boiling point of the reductant material at atmospheric pressure or the sintering temperature of the produced elemental material or alloy.

    摘要： Methods and apparatuses for producing a solid metallic composition by reacting a gaseous metal halide with a reducing agent are described. The method generally includes reacting a gaseous metal halide with a reducing agent in a manner effective to form a nonsolid reaction product, wherein the metal halide has the formula MXi, in which M is a metal selected from a transition metal of the periodic table, aluminum, silicon, boron, and combinations thereof, X is a halogen, i is greater than 0, and the reducing agent is a gaseous reducing agent selected from hydrogen and a compound that releases hydrogen, and combinations thereof; and solidifying the reaction product, thereby forming a metallic composition comprising M that is substantially free from halides. In another aspect, a method for producing a solid metallic composition is provided in which a metal subhalide is reduced by reaction with a gaseous reducing agent to form a nonsolid reaction product; which is then solidified to form a metallic composition comprising the metal that is substantially free from halides, oxygen, nitrogen, and carbon. An apparatus for producing a metallic solid composition is also provided that includes a source of a metal halide having the formula MXi; a source of a reducing agent wherein the reducing agent is a gaseous reducing agent selected from hydrogen and a compound that releases hydrogen, and combinations thereof; a reactor in communication with the metal halide and the reducing agent sources, wherein the reactor provides conditions effective to carry out a gaseous reaction between the metal halide and the reducing agent to form a nonsolid reaction product; and a means for solidifying the reaction product to form a metallic composition comprising M that is substantially free from halides. The invention may be used to produce high-purity metallic compositions, particularly titanium particles and alloys thereof for use in powder metallurgy applications.
