    摘要: The subject invention pertains to methods for processing a solid material (M1X) comprising a solid solution of a non-metal species (X) in a metal or semi-metal (M1) or a compound between the non-metal species and the metal or semi-metal is immersed in a molten salt (M2Y). A cathodic potential is applied to the material to remove a portion of the non-metal species by electro-deoxidation. To remove the non-metal species at lower concentrations, a source of a reactive metal (M3) is immersed in the molten salt and is electronically connected to the material. Reactions occur at the material, where the non-metal species dissolves in the salt, and at the reactive metal, which reacts with the non-metal species dissolved in the salt to form a reaction product more stable than a compound between the non-metal species and the metal or semi-metal (M1). The non-metal species is thus removed from the solid material.

    摘要: A process for minimising reoxidation of reduced material is disclosed. The process applies to reduced material that has been formed by a process of electrochemically reducing a metal oxide feed material, such as titania, in a solid state in an electrolytic cell containing a molten electrolyte. The process for minimising reoxidation includes applying an electrical potential to reduced material at least while the reduced material remains immersed in the molten electrolyte.

    摘要: A method of making sheet bar and other precursors of formed products to be made by extensive working. The method includes providing a powder metal, preferably under 100 PPM oxygen content of non-spherical particles, compacting the powder into a coherent precursor form of at least 100 pounds, whereby a precursor is provided enabling extended fabrication to a finished product form. The finished product is resistant to breakup in fabrication due to oxide inclusion effect and produces a low oxygen end product. The method can process multiple species of metals that include at least one higher melting metal and one lower melting metal to produce an alloy or micro-composite of the metals as worked, where one metal is preferably a refractory metal (Ta, Nb, W, Wo, Zr, Hf, V and Re). The process is controlled to cause powder of the higher melting metal to be extended into a fibrous form.

    摘要: Gallium is zone refined in a stationary, vertical, double annulus refiner. Impure gallium is contained between walls of a first annulus that are made of a material that does not impart impurities to the gallium. At least one of the walls is made of a flexible material. A cooling fluid is circulated through a second annulus enveloping the first annulus. The gallium is zone refined by moving through the gallium ingot one or more molten zones formed by radio frequency waves from at least one reciprocating radio frequency heating induction coil. After the necessary number of passes, the ingot is cropped without introducing contaminants and refined gallium with purities between 79 and 89 is recovered. LEC single crystal GaAs made with the so refined gallium has very uniform electrical characteristics.
