    摘要: A method for refining a titanium metal containing ore such as rutile or ilmenite or mixtures to produce titanium ingots or titanium alloys and compounds of titanium involves production of titanium tetrachloride by processing the ore with a chlorinating procedure and removing various impurities by a distillation or similar procedures to form a relatively pure titanium tetrachloride. Thereafter, the titanium tetrachloride is introduced continuously into a reactor at the focal point of a plasma under atmospheric pressures of inert gas along with molten metallic reductant for the initial reduction of gas phase titanium tetrachloride into molten titanium drops which are collected in a set of skulled crucibles. Thereafter, further processing is carried out at atmospheric pressures in under inert gas where the titanium is heated by plasma guns to maximize titanium purity and, in a final optional stage, alloying compounds are added under the same controlled environment and high temperature conditions.

    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 process and system for producing tantalum or other valve metal particles is provided comprising forming tantalum particles in a reduction process carried out in a reactor vessel, and using a siphon to transfer fine tantalum particles out of the reaction mixture to a recovery vessel. This particle transfer can occur while the reaction mixture is agitated. The tantalum particles can be automatically withdrawn when the reaction mixture has a depth level greater than the fluid level of the tantalum fine particle recovery vessel, and outflow automatically stops when the fluid levels of the reactor and particle recovery vessel equilibrate. Tantalum or other valve metal powders made by the processes, and capacitors made with valve metal powders are also provided.
