Abstract
Continuous-wave CO2 laser irradiation into gaseous methyldisiloxanes [(CH3)nH3−nSi]2O (n
= 2,3) at 1000 °C yields nanosized Si/C/O–carbon composites and at 2000 °C affords SiC–Si/C/O–carbon composites. The results demonstrate the feasibility of the direct production of silicon carbide from disiloxanes and suggest that the laser-induced homogeneous
