Abstract :
Microstructural properties of nanosized particles produced by CO2 laser synthesis from gaseous precursors, are studied by different techniques. Results on the characterization of binary (SiC and Si3N4) and ternary (Si/C/N) ultrafine powders are presented. The evolution of the chemical composition and microstructure, after heat treatments in different atmospheres, is investigated in order to study and to improve the stability of these materials.
