The change in the temperature of the submicron carbon-black particles formed behind the reflected shock wave as a result of the pyrolysis of ethylene was investigated by the photoemission method. It has been established that the temperature of the carbon black substantially differs (by a value of the order of 400–600 K) from the temperature of the gas medium in which it is formed and grown. It is shown with the use of scanning electron microscopy that the average diameter of the carbon nanoclusters forming the carbon black comprises 55–30 nm at a pyrolysis temperatures of 2100–2800 K. The porosity of the primary nanoparticles is equal to 0.95–0.97.
