摘要：从含有杂质的镓原料中分离杂质的方法,该方法是一边搅拌装在容器内的液态镓原料,一边使筒状的凝固界面从该容器的内壁面朝着容器中央的方向逐渐凝固,并在容器内的全部原料凝固之前使存在于容器中央部分的液相与凝固相分离。另外,把与液相分离后的凝固相作为镓原料,根据需要将上述方法反复进行多次。通过分析与凝固层分离的杂质浓缩Ga中的杂质浓度,可以获得一种适合于制备化合物半导体的金属Ga。

摘要： A method and system is used to process slag material to yield by-products including a finished iron rich product and a finished low iron fines product. The by-products may include a finished high iron product and a finished medium iron product. The method and system include size classifying the material into a plurality of sized groups prior to using magnetic separation to separate at least one of the sized groups into two portions having differing magnetic susceptibilities. The method and system may include more than one phase of size classifying the material into a plurality of sized groups and using magnetic separation to separate at least one of the sized groups into portions, where the average size of the material remaining after one phase is reduced prior to the subsequent phase.

摘要： The present invention concerns a high vacuum in-situ refining method for high-purity and superhigh-purity materials and the apparatus thereof, characterized in heating the upper part and lower part of crucible separately using double-heating-wires diffusion furnace under vacuum, thereby forming the temperature profile which is high at upper part and low at lower part of crucible, or in reverse during different stages; then heating the crucible in two steps to remove impurities with high saturation vapor pressure and low saturation vapor pressure respectively in efficiency; and obtaining high-purity materials eventually. The whole procedure is isolated from atmosphere, reducing contamination upon stuff remarkably. The present invention could provide products with high-quality and high production capacity, which are stable in performance, therefore is reliable and free from contamination. The present invention is appropriate for manufacture of high-purity and superhigh-purity materials, particularly for manufacture of high-activity high-purity materials.

摘要： A method for purifying metal M1 particles manufactured by an electrochemical reduction process, the method comprising the steps of introducing the metal M1 particles into a heat source (13) at a temperature substantially equal to or higher than the melting point of M1 so as to cause vaporisation of some or substantially all of the contaminating impurities present, removing the vaporised Impurities from the vicinity of the particles, and cooling the purified metal M1 particles. The purified particles can be used directly in lower temperature powder metallurgy processes and have fully dense spherical particle morphology, imparting good flowability. The purification process can also be incorporated as an integral stage of sheet or stock production processes based on particle feedstock's that have been produced by electrochemical reduction.

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 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： The microstructure of titanium is refined by inducing a high temperature transformation from .alpha.+.beta. to .beta. and back to .alpha.+.beta. by diffusing hydrogen into and then out of the metal while maintaining the metal above the temperature of hydride formation. The titanium is heated to a temperature just below the .alpha.+.beta. to .beta. transformation temperature, and hydrogen is diffused into the metal thereby inducing the phase change. The hydrogen is diffused out of the metal again inducing a phase change. When the hydrogen has been removed, the metal is allowed to cool to room temperature.
摘要翻译：通过在将金属保持在高于氢化物形成温度的前提下，通过将氢扩散到金属中，然后通过引入从α+β到β并回到α+β的高温转化来精炼钛的微观结构。将钛加热到刚好低于α+β至β相变温度的温度，并且氢扩散到金属中，从而引起相变。氢气再次从金属中扩散出来，导致相变。当氢被除去时，使金属冷却至室温。
