Several evidences of fullerenes present in the furnace carbon black formati
on process ave reported. These fullerene structures am particularly abundan
t in some experimental furnace blacks. Our observations could be related to
the discovery of fullerenes in soot-forming flames in the literature. If i
s believed that either fullerenes or fullerene precursors could play an imp
ortant role in carbon black formation, especially in the inception step.
