Abstract

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.
