Abstract
A powder for the production of a superconducting component. The powder includes NbxSny, where 1≤x≤6 and 1≤y≤5, and three-dimensional agglomerates having a particle size D90 of less than 400 μm, as determined via a laser light scattering. The three-dimensional agglomerates have primary particles which have an average particle diameter of less than 15 μm, as determined via a scanning electron microscopy, and pores of which at least 90% have a diameter of from 0.1 to 20 μm, as determined via a mercury porosimetry.
