A PROCESS FOR THE SYNTHESIS OF NANOSTRUCTURED METALLIC HOLLOW PARTICLES AND NANOSTRUCTURED METALLIC HOLLOW PARTICLES

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 (N2 and H2)) 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
