The role of carbon black is especially important in cokeless metallurgy. Carbon black can be isolated at less hot zones (less than 720) in metallurgical ovens according to equation of Buduara: 2CO = C + CO₂. The particles of carbon black obtained by the reaction of Buduara are characterizing with complicated open-work structure including globular amorphous parts and graphitized crystalline elements connected by crosspieses with size in nanometric range (0.1μm - 3 μm). The carbon black is characterizing with increased Gibbs’s energy and high kinetical activity because of it’s dispersed and amorphous structure.
