Carbon black - Wikipedia

Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content.

Three Main Properties of Carbon Black

Three Main Properties of Carbon Black. The size of spheric particles is called "particle size," and the size of the particle chain is called "structure.". Various functional groups such as the hydroxyl or carboxyl group are found in the surface of carbon black, and their amount or composition is called "surface chemistry.". These three - "particle.

6.1 Carbon Black - US EPA

6.1 Carbon Black 6.1.1 Process Description Carbon black is produced by the reaction of a hydrocarbon fuel such as oil or gas with a limited supply of combustion air at temperatures of 1320 to 1540°C (2400 to 2800°F). The unburned carbon is collected as an extremely fine black fluffy particle, 10 to 500 nanometers (nm) in diameter.
