Variation of Oxygen-to-Carbon Ratio in Oxyacetylene Flame

We present micro-structural and surface analysis of carbon soot using variation in C 2 H 2 to O 2 ratio in oxyacetylene flame torch. Preliminary analysis indicate that at higher oxygen content, formation of SiO 2 nanotubes and amorphous-SiC like structure take place while at higher C 2 H 2 flame con...

Zusammenfassung:	We present micro-structural and surface analysis of carbon soot using variation in C 2 H 2 to O 2 ratio in oxyacetylene flame torch. Preliminary analysis indicate that at higher oxygen content, formation of SiO 2 nanotubes and amorphous-SiC like structure take place while at higher C 2 H 2 flame content, we observe majority of amorphous carbon with an evidence of some amorphous sp 3 hybridization.
