Synthesis of ceramic nanoparticles by laser pyrolysis: From research to applications

摘要

Nanoparticles are the building blocks of many approaches for realizing nanostructured materials and devices. The technique of CO_2 laser pyrolysis of gas- or vapour-phase precursors for the synthesis of nanoparticles has proven to be a very flexible and versatile technique which permits to cope with several challenges in different sectors of nanotechnology. Different kinds of pyrolytic nanopowders with average size in the range 5-60 nm and a narrow size distribution, have been produced and tested for the fabrication of structural materials and/or for functional applications in various fields. Here we report new results on the synthesis of SiC, TiO_2 and SiO_2 nanoparticles for energetic applications and cultural heritage preservation.
