Claim 9:
10. The sintered molybdenum part according to claim 1, wherein the following applies at least at a grain boundary section of a large angle grain boundary and an adjoining grain:
a total proportion of carbon and boron in a region of said grain boundary section is at least one and one half times a total proportion of carbon and boron in a region of a grain interior of said adjoining grain, measured in atom percent by three-dimensional atom probe tomography;
a three-dimensional, cylindrical region having a cylinder axis running perpendicular to said grain boundary section and a thickness running along said cylinder axis of 5 nm which, relative to a cylinder axis direction, laid centrally around said grain boundary section is selected for said region of said grain boundary section; and
a three-dimensional, cylindrical region having identical dimensions and an identical orientation and having a center 10 nm away from said grain boundary section in said cylinder axis direction is employed for said region of said grain interior.
