摘要：
The present invention relates to a process for the synthesis of nanostructured metallic hollow spherical particles, in which the metal is deposited onto sacrificial masks formed in a polymeric colloidal solution by the electroless autocatalytic deposition method (deposition by the present process releases only gaseous products (N
2 and H
2 )) during the oxidation thereof, which evolve without leaving contaminants in the deposit)). The particulate material composed by nanostructured metallic hollow spherical particles with average diameter ranging from 100 nm to 5 µm and low density with respect to the massic metal, and a process for compacting and sintering a green test specimen formed by the respective particulate material are also described. 1
