In production of sintered bodies of particulate metal, especially porous sintered bodies, from particles of metal having a refractory oxide coating, a minor proportion of a flux is mixed with the particulate metal before sintering to aid in removing oxide from surfaces of the metal particles. The particulate metal may be aluminum, with which there may be mixed a minor proportion of particles of an alloying element. The flux may be a mixture of potassium fluoaluminate complexes; the residue of this flux, after sintering, provides a coating that aids in protecting the sintered article against corrosion.
