Peroperties: Carbon black is a material produced by the incomplete
combustion of heavy petroleum products such as FCC tar, coal tar,
ethylene cracking tar, and a small amount from vegetable oil.
Carbon black is a form of amorphous carbon that has a high
surface-area-to-volume ratio, although its surface-area-to-volume
ratio is low compared to that of activated carbon. It is dissimilar
to soot in its much higher surface-area-to-volume ratio and
significantly less (negligible and non-bioavailable) PAH
(polycyclic aromatic hydrocarbon) content. Carbon black is used as
a pigment and reinforcement in rubber and plastic products.
