The existing models for the structure and inception processes of carbon bla
ck particles are analyzed taking into account the experimental data on the
cluster formation. A new model of the formation of carbon black particles i
s proposed. The inference is made that single-layer fullerenes being the mi
nimum possible closed carbon black particles serve as nuclei of large-sized
carbon black particles. These particles grow via the deposition of carbon
layers on the surface of fullerenes with defects. The defects fulfill the r
ole of seeds that give rise to the front of the layer growth. The defect-fr
ee fullerenes do not take part in the carbon black formation due to the the
rmodynamic stability as a result of structural perfection. The primary carb
on black particles-globules-are many-layer formations with a hole in the ce
nter whose size and configuration match the size and configuration of the i
nitial fullerene nucleus. The layers in the form of concentric spheroids in
serted into each other are composed of distorted and defect carbon networks
. The flatest parts of several outer layers of carbon black particles are t
he regions of the coherent X-ray scattering. (C) 2000 MAIK "Nauka/Interperi
