The Properties of Nanodispersed Carbon Black Particles After Thermal Treatment

The effect of thermal treatment at the temperature ranging from 800 to 2800°С on electrical resistance, specific adsorption surface and Raman spectrum of nanodispersed carbon black samples was investigated. It was determined that during the temperature increase, at first, the sample electrical resistance decreases (till the temperature of 1100 - 1600°С), and then rises. Specific adsorption surface decreases to geometrical one with the increase of the treatment temperature. New band appears within the range of ∼ 2570 cm-1 in Raman spectra after the thermal treatment at the temperature of 2000°С and higher.
