Laser photo induced reactions from gaseous precursors have been applied to the synthesis of nanosized silicon carbonitrides and γ-alumina based powders. Silicon carbonitrides with different structures and chemical compositions have been produced by changing the reactant gases or their relative concentrations. The structural and chemical evolution have been studied by thermal treatments in Ar and N2 atmosphere. The results confirm the applicability of this powder for industrial applications. Concerning the γ-alumina powder, changes in the reactants concentration ratio have shown to influence both the process yield and the composition of the outcoming powders. Nitrogen or carbon rich γ- alumina powders (Al3O3N, Al2OC) have been synthesized. Some recent and encouraging results on the thermal properties of laser produced silicon carbide are also presented.
