Nanometric Si/C/N composite powders: Laser synthesis and IR characterization

Synthesis of SiCNAl(O) pre-alloyed nanopowders by pyrolysis of an aluminosilazane aerosol

“…7 On an other hand, nanostructured materials can be fabricated if an ultrafine multielement powder method is used. Several teams have worked and are still working on this route, [8][9][10][11][12][13] mainly using the laser-pyrolysis process, but their investigations concern mixtures of non-miscible precursors. They did not realize an unique hybrid precursor containing metallic elements needed for sintering.…”

Reduced-Pressure Chemical Vapor Synthesis of Nanocrystalline Silicon Carbide Powders

“…The advantages of the reactions in the gas phase are very short process times and powders with narrow particle size distribution at small mean values and high purity. The energy required for the decomposition of volatile silicon compounds in gas phase reactions forming ultrafine SiC particles can be provided by laser radiation, [14][15][16][17][18][19][20][21][22][23][24][25] plasmas, [26][27][28][29][30] or thermally. [31][32][33][34][35] Tetramethylsilane (TMS) is a well-known precursor for the production of SiC films by CVD [36] either in low-pressure [37][38][39][40] or plasma-assisted [41,42] processes.…”

Synthesis of Si–C–N coatings by thermal Plasmajet chemical vapour deposition applying liquid precursors

“…13 Laser-assisted methods are usually applied in the field of powder production. [14][15][16][17][18] Furthermore, dip-coating processes can be applied; these are based on the wetting and physical adsorption of a liquid precursor into which a substrate is submerged. During a heat treatment, the precursor is pyrolysed and the SiC coating is formed.…”
