Motivated by recent experimental investigations of carbon black surface roughness and several new results emphasising the role of fullerene like precursor structures in carbon black formation, a first attempt for modelling the nucleation and surface growth mechanisms during furnace black processing is presented, It is shown that the experimentally detected universal surface morphology independent of grade number can be explained on the one side by numerical simulations of molecular ballistic deposition models and on the other side by the anisotropic KPZ equation, A particular solution of this equation, i.e. a circular shaped and pyramidal layered Toom interface, compares fairly well to the morphology obtained from TEM images of carbon black on nanoscopic length scales.
