摘要： A metallic alloy having at least two metallic constituents is produced by first furnishing (20) at least two non-oxide compounds, wherein the non-oxide compounds collectively comprise each of the metallic constituents, and wherein each of the non-oxide compounds is soluble in a mutual solvent (22). The method further includes dissolving (24) the non-oxide compounds in the mutual solvent to produce a solution containing the metallic constituents, thereafter heating (26) the solution to remove the mutual solvent and oxidize the metallic constituents to produce a mixed metallic oxide, thereafter cooling (28) the mixed metallic oxide to form a substantially homogeneous mixed metallic oxide solid mass, and thereafter chemically reducing (30) the mixed metallic oxide solid mass to produce a metallic alloy. The metallic alloy may be consolidated or otherwise processed (32).

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： The present invention relates to a method of reducing a metal-oxygen compound wherein carbon acts as a reducing agent, comprising in a first reaction stage, passing CO gas into a reaction chamber containing said metal-oxygen compound, under conditions such that CO is converted to solid carbon and carbon dioxide thereby introducing the solid carbon so formed to said metal-oxygen compound, and in a second reaction stage, causing said carbon, which is introduced to the metal-oxygen compound in said first reaction stage, to reduce said metal-oxygen compound, wherein there is present, at least in said second reaction stage, a first promoter material effective to promote the reduction of said metal-oxygen compound, the first promoter material comprising a first promoter metal and/or a compound of a first promoter metal. The invention also relates to an apparatus for carrying out the reduction of a metaloxygen compound wherein carbon acts as a reducing agent.

摘要： A hollow partition wall (4) is employed to feed carbon material to an underflow of a carbothermic reduction furnace used to make aluminum. The partition wall (4) divides a low temperature reaction zone (2) where aluminum oxide is reacted with carbon to form aluminum carbide and a high temperature reaction zone (3) where the aluminum carbide and remaining aluminum oxide are reacted to form aluminum and carbon monoxide.
