    摘要: The present invention relates to a stepwise method for the production of titanium-aluminum compounds and some titanium alloys and titanium-aluminum inter-metallic compounds and alloys. In a first step an amount of aluminum is mixed with an amount of aluminum chloride (AlCl3) and then an amount of titanium chloride (TiCl4) is added to the mixture. The mixture is heated to a temperature of less than 220° C. to form a product of TiCl3, aluminum and AlCl3. In a second step, more aluminum can be added if required, and the mixture heated again to a temperature above 900° C. to form titanium-aluminum compounds. This method results in the production of powdered forms of titanium-aluminum compounds with controllable composition. Suitable reactor apparatus is also described.

    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: Processes for producing valve metal are described, in which valve metal oxide is converted to valve metal using a vapor-phase transport agent to form a gaseous valve metal species in the presence of a solid getter material. Also described is the valve metal so produced, and anodes prepared from the valve metal, as well as electrolytic capacitors using the anodes.

    摘要: A mass of solid aluminum carbide containing product is produced by a process in which a mixture is formed of an aluminum containing material and a carbonaceous material consisting of, containing or yielding carbon. Then the resulting mixture is heated to a temperature sufficient to react carbon of the carbonaceous material with the aluminum of the aluminum containing material to produce solid aluminum carbide. The solid aluminum carbide then is able to be heated with an aluminum compound selected from Al2O3, Al4CO4, AlO, Al2O and mixtures thereof, to produce aluminum metal and carbon monoxide.
