Abstract

A powder-metallurgical sintered molybdenum part which is present as a solid body has the following composition: a molybdenum content of ≥99.93% by weight, a boron content “B” of ≥3 ppmw and a carbon content “C” of ≥3 ppmw, with a total content “BaC” of carbon and boron being in a range of 15 ppmw≤“BaC”≤50 ppmw, an oxygen content “O” in a range of 3 ppmw≤“O”≤20 ppmw, a maximum tungsten content of ≤330 ppmw and a maximum proportion of other impurities of ≤300 ppmw. A powder-metallurgical process for producing such a sintered molybdenum part is also provided.
