摘要： The present disclosure provides a preparation method of a contact material with high thermal stability and low contact resistance based on an MgAgSb-based thermoelectric material and relates to the field of the contact materials preparation. The present disclosure aims to solve the problem of failure to achieve long-term stability for the MgAgSb/Mg3Bi2 device due to the fact that a contact material used by MgAgSb is Ag and MgAgSb may easily yield Ag3Sb in an Ag-rich environment at present. The method includes: at step 1, preparing MgCuSb nano-powder; at step 2, preparing MgCu0.1Ag0.87Sb0.99 nano-powder; at step 3, preparing MgCu0.1Ag0.87Sb0.99—Mg3.2Bi1.5Sb0.5 thermoelectric generation device. The present disclosure is applied to preparation of a contact material with high thermal stability and low contact resistance based on an MgAgSb-based thermoelectric material.

摘要： Provided is a jig for supporting a plate-shaped workpiece made of a sintered compact when subjecting the workpiece to a steam treatment. The jig is provided with a bottom plate configured to support a plurality of workpieces in a stacked manner, and a guide rod erected on one surface of the bottom plate to position the stacked workpieces. An opening configured to allow supplied steam to pass through downward is formed in a vicinity of a portion of the bottom plate on which the workpiece is to be supported.

摘要： The embodiments relate to a method for the production of a refractory metal component by casting. The method includes providing a slip that contains a powder including at least one refractory metal or a compound thereof, in addition to at least one binding agent. The method further includes processing the slip by casting, (e.g., film casting or slip casting), to form at least one slip coating, the slip being devoid of a metal binding agent. A component was produced by this method. The embodiments may be used, in particular, on X-ray tubes, accelerator targets, or fusion reactors, such as for a surface of an X-ray anode, or a wall of a fusion reactor.
