Oxidation of carbon powders by steam

The oxidation kinetics of a diamond powder, P-803 carbon black, and the OSUNT raw material (obtained by electric arc synthesis of single-walled carbon nanotubes) in a stream of steam in the temperature range 600–1315 K was studied. The parameters of the kinetic equations were determined. The temperature dependence of the oxidation rate was found to consist of three regions with different activation energies.
