Variation of Oxygen-to-Carbon Ratio in Oxyacetylene Flame

reportActive / Technical Report | Accession Number: ADA496367 | Open PDF

Abstract:

We present micro-structural and surface analysis of carbon soot using variation in C2H2 to O2 ratio in oxyacetylene flame torch. Preliminary analysis indicate that at higher oxygen content, formation of SiO2 nanotubes and amorphous-SiC like structure take place while at higher C2H2 flame content, we observe majority of amorphous carbon with an evidence of some amorphous sp3 hybridization.
