摘要： A method for separating a certain metal from a raw material including a mixture of the metal and an element which has a lower vapor pressure than the metal. The raw material including the mixture of the metal and the element is heated so as to cause a first vapor including the metal to be evolved. This first vapor is passed through a throttling means in which it undergoes adiabatic expansion and is rapidly cooled so that at least part of it is reduced to a liquid containing the metal. This liquid is reheated so as to cause a second vapor including the metal to be evolved. And the second vapor is cooled to collect the metal. An apparatus is also disclosed for performing this method.

摘要： Fine powder of an alloy of two or more metals is made by vaporizing each of these metals in its own vaporization chamber, mixing each of the metallic vapors with an inert carrier gas, and then adiabatically expanding each of the mixture gases through its own nozzle, which preferably is a convergent-divergent nozzle. Jet flows from the nozzles are collided together, after having been very rapidly cooled by this adiabatic expansion, and thereby the metal vapors in the jet flows are quickly condensed into very fine alloy particles. Optionally the combined flows from the jets are directed against an alloy powder collecting means, which may be a collection plate, but preferably is a bath of oil which entrains the alloy particles and keeps them from agglomerating together by partially neutralizing their surface activity. Thus fine alloy powder with particle diameters of the order of a few hundreds of angstroms can be economically produced.

摘要： A case nitrided aluminum product is produced by contacting an aluminum product with a nitriding agent at a part of a surface thereof at least, and by nitriding the aluminum product at the surface with an ambient gas at a temperature of a melting point of the aluminum product or less while keeping the aforementioned contact. The nitriding agent includes an aluminum powder, and the ambient gas virtually includes a nitrogen gas. The resulting nitriding layer has a depth of 5 micrometers or more, and it exhibits a case hardness of from 250 to 1,200 mHv. Thus, it is possible to form the deep and hard nitriding layer on the aluminum product with ease under the conditions where it has been said to be too difficult to nitride aluminum products. The case nitrided aluminum product can appropriately make sliding parts which require high wear resistance.

摘要： A process for producing aluminum nitride includes a step of holding an aluminum powder in a nitrogen atmosphere whose nitrogen gas pressure falls in a range of from 105 to 300 kPa, thereby developing a nitriding reaction at a temperature of from 500 to 1,000° C., wherein a reaction controller gas, controlling the development of the nitriding reaction, is supplied into a reactor chamber in which the aluminum powder is accommodated. In the production process, the reaction controller gas is included in the nitrogen atmosphere in the development of the nitriding reaction. Accordingly, the development of the nitriding reaction is controlled so that it is possible to develop the nitriding reaction at a lower temperature. As a result, it is possible to produce an aluminum nitride powder whose particle diameters are fine.
