Abstract (en)

[origin: WO2019060932A1] The invention relates to a powder-metallurgical sintered molybdenum part, in the form of a solid body, which has the following composition: a molybdenum portion of ≥ 99.93% by weight, a boron portion "B" of ≥ 3 ppmw and a carbon portion "C" of 3 ppmw, wherein the total portion "B+C" of carbon and boron is in the range of 15 ppmw ≤ "B+C" ≤ 50 ppmw , an oxygen portion "O" in the range from 3 ppmw ≤ "O" ≤ 20 ppmw, a maximum tungsten portion of ≤ 330 ppmw and a maximum portion of other contaminants of ≤ 300 ppmw. The invention further relates to a powder-metallurgical method method for producing such a sintered moybdenum part.
